No Touching Please - Contactless sensor buttons

I chanced upon some contactless sensor buttons at elevators/lifts, most likely installed during the covid pandemic to prevent the transmission of virus and bacteria through contact of various surfaces in common areas.




This piqued my interest, as it is something that has been adopted out of necessity and yet makes so much sense, for a surface that is usually touched by many individuals throughout the day.

A quick search online revealed that there are several kinds of contactless button solutions: static infrared sensors with lights or a buzzer, and sensors with kinetic touches to replicate the actual pushing of the button.

Benefits of contactless sensor buttons for lifts/elevators include saying goodbye to the incessant hammering of the buttons, because, let's face it: pressing a button faster and repeatedly doesn't make the lift/elevator move faster, as well as a reduced risk of accidentally pressing the alarm and intercom buttons, which may still retain the tactile contact buttons as the frequency of use is expected to be low and to prevent accidental activation via sensor buttons.

There are currently many types of sensors designed in a lift/elevator, mostly to detect obstruction or motion around the lift/elevator doors, so sensors are not an entirely new technology or concept to be deployed.

According to Fact.MR, the global Contactless Elevator Market is valued at around US$1.85 billion in 2022, accounting for approximately 4.5% of the global elevator market. The development of smart infrastructure and refresh of elevators in old skyscrapers are expected to provide an uplift in the demand for contactless lift/elevator.

Probably one key factor keeping the adoption rate of contactless sensor elevators low is the premium one can expect to pay as compared to a 'normal' lift/ elevator, with premiums running anywhere between 50% to 150% of the cost for a standard lift/ elevator model. This is one space to watch, as individual sensors procured at wholesale prices are relatively inexpensive today. 

Let me know what you think about contactless sensor buttons!

Water, Water Everywhere

 


When I saw this sight across the causeway, two things came to mind:

1. It's easy to read the water meter without having to get into the drain (a confined space)

2. Bad design, it's a trip and fall hazard and prone to damage by passers-by

Even worse, corroded pipes do not seem to have been removed when replacement pipes are laid, and are just sticking out of the drain cover.

It seems that most drains and water pipes and water meters in Singapore are designed differently.

PUB, NEA and LTA are key stakeholders in the drainage system: PUB to ensure the functionality of the drains in conception storm water, NEA in ensuring no formation of stagnant water which may lead to mosquito breeding, and LTA in maintaining the drain covers as they form part of the footpaths. There are a total of 8,000 drain covers and manhole covers in Singapore.

Water pipes also do not seem to run inside the drain and storm water and waste water are separately conveyed in the drainage system. Water meters are also usually installed at a convenient location for ease of reading. 

Just some food for thought.

What lies beyond this door?

 


Over the weekend and across the causeway, I chanced upon probably one of the most interesting doors. It didn't seem to lead anywhere and didn't seem to serve any purpose other than to satisfy fire regulations. What is the most interesting door you have ever come across?

Hello World v2.0

Inspired to resume blogging to share my personal observations and musings after chatting with a friend. It has been a not-so-brief hiatus and I look forward to exciting times ahead!

Just back from the SMU Stageit production of 'A Sword has Two Edges', a rendition of the Lu Bu-Dong Zhuo feud featured early on in the classic 'Romance of the Three Kingdoms' series.

Overall, the play was pretty good, having blended all the elements of suspense, action and humour pretty well into an enjoyable play.

Rating: 85%

Also, having caught the exclusive premiere of 'Thank you for smoking', I think it's an act by Big Tobacco to legally throw in a few gasping advertisements into a major Hollywood production, and in good humour at the same time.

Updates:

Due to the passing of my beloved grandma in February, there has been no updates for the past three months.

Exams are finally over (Okay, so it has been nearly two weeks since), and it's now time to descend into the entertainment abyss (Read "Gaming zone").

Will be away from this Saturday, until the 23rd.

Just thought it would be good to rearrange some of the categories, to make the site more readable:

"All cats are bats
All bats are rats
>All cats are rats"
This is a valid argument! (Though unsound it may be)

Supper with V Gang (okay, so only May, Ivan and Ruiyi turned up) at Simpang Bedok.

Menu for the day:
Chicken rice paprik (Black pepper chicken with nasi goreng)
Egg Prata
Chicken Masala Murtabak (Chicken Prata with cheese and onions)
Tissue/ Paper Prata (Cone-shaped prata)
Prata Bomb (Fattening Prata with lotsa butter)
Roti John Special (French loaf with sweet sauce)

After much deliberation, the judges decided in a 3 to 1 vote that the Chicken Masala Murtabak was the best order (with a unanimous 4-0 vote on the most disappointing item - The Prata Bomb). In second place was the Roti John Special. Considering the relatively reasonable ($5/person) cost of the meal, it's certainly worth another go in future.

After supper, I wanted to grab a drink, so we went to the Shop 'N Save nearby. What awaited me was a frantic search for bottled and canned drinks, as I spent five minutes racing up and down the various aisles before reaching the 'beverage' aisle. Lo and behold! 'Beverage' in supermarket language means "Milo, tin", "3-in-1 coffeemix" and "Teabags". Frustrated by the layout of the supermarket, I stormed out without making a purchase (I found out on my way out that drinks were sold outside the store).

Went to Marina Square's Long John Silver's for dinner with JM and ZR. From past (bad) experience, I decided against ordering any of the 'special' meals, instead opting for the safer Combo meal. JM tried the grilled fish rice (with rice and fries), and ended up having to wait fifteen minutes before being served. And the worst thing? He had TWO servings of rice and one of fries. Apparently, the counter staff did not inform him that 'side orders' were independant of the main item (fish AND rice), so he ordered rice anyway.

We're getting better at Knights of Valour and Photo Hunt. Woo... :)

Went out again with ZR and mum at one in the morning to engage in the Lunar New Year crowd at Serangoon Central. The G'Value store has been rebranded (It's now a Shop 'N Save outlet) and it now displays poultry in freezer-fridges.

6 mods, 5 credits, 4-day week ,3 exams, 2nd sem, just 1 of me.

Been busy with Biz law the past week.

Happy 21st Sharon!
Saturday was lunch at Junction 8 with Sharon (Sakae Sushi). We had handrolls, beef soup ('twas sweet! but very tasty) and unagi omelette. Yum yum. Unfortunately, I had to rush down to school for biz law meeting, which dragge on till 6.

TKD reunion dinner
Response was g-reat! 25 people atended the dinner (We were short of space, so a third table had to be set up). Following a sumpteous dinner of yummy fried baby sotong, deep fried fish and cereal prawns, we headed down to Marina Square (a short walk away from school. Hoorah!) where we proceded to play arcade games and pool while waiting for our turn at bowling. Sir Peter was an extraordinary bowler, after he showed us a thing or two about the finer points of bowling. :)

Yup, back to work on Biz Law!

Just a thought

"What's the main cause for backaches in modern Singapore?"

This question popped to mind as I was travelling on board a public bus on Friday night. Recalling the high incidence of 'chronic lower back pain' at Gedong, I was not surprised that I came to a conclusion that it is all about posture, and buses are partly to be blamed for the aggreviation of such conditions. Just look at how youths and teenagers are seating nowadays: Slouched to the shape of a capital 'U', they adopt this position so that it is more comfortable for their (long, and sometimes not very long) legs (or so they seem, for this position hyperextends the spinal chord, increasing stress on the back). Tsk tsk.

Had an insightful exchange with NTU's TKD group yesterday night, a collaboration between our coach and theirs, to gauge our standard as well as 'bond' as one martial arts family.

Got the chance to spar twice (3 rounds of 1 minute each), and was fortunate to be up against 2 rather defensive exponents. Techniques and strategies will be formulated over the next few weeks in the build up to the IVP (hosted by NTU this year) after the exchange training session.

NTU's team had a few SAFSA fellas, and a great deal of black belters (no kidding!). Christine had her face kicked (and her gums bled!), but other than that, no major injuries on our side.

After last Wednesday's extended schooling hours (From 8.30 am to 10.45 pm), I hope there won't be another day as long as this in future. Ever.

Our Business, Government and Society class was registered for the George Soros seminar at the Raffles City Convention Hall (George Soros & A Global Open Society - A Dialogue with a New Generation : Full commentary by Agagooga).

Am finding Business law more interesting. Probably due to the fact that I have managed to get my hands on the readings (Book, scripture, whatever you may call it) and actually got to read it. This is in stark contrast to the first lesson, where the Prof was, at least in my opinion, sprouting incomprehensible latin!
