Real problems. Engineered solutions.
Four representative deployments showing how we customize our standard products for India's most demanding environments - large hospital chains, international airports, IT campuses and multi-branch BFSI networks.
Queue Management System

Queue Management System
Deployed at
One token, every counter.
We rebuilt the patient queue at Ramiah and Sakra so that a token issued at billing automatically follows the patient across lab, X-ray, pharmacy and every downstream counter - no second token, no re-queuing.
The Challenge
Hospitals were running stand-alone token systems. A patient took a fresh token at every department - billing, lab, X-ray, pharmacy - and joined the queue from scratch each time. The token expired the moment it was called. The result was long cumulative waits, repeated paperwork at every counter, and a fragmented patient journey.
What we engineered
- Token forwarding. One token issued at the first touchpoint automatically follows the patient across every downstream counter.
- Self-service tab kiosks. At Sakra, patients pick a department on an entry tablet and receive their token via SMS - the dispenser line itself disappears.
- Multi-counter calling. The same token can be called from any free counter, enabling instant load-balancing and clean lane-opening during peaks.
- Centralized supervisor dashboard. Live wait-times, average service time per counter and abandonment alerts surface to a single screen.
Key innovation
A single dispenser scales to dozens of downstream queues. We recommend a 30-queue ceiling not because the platform can't take more, but because that's where the patient experience stays effortless.
Nurse Calling System

Nurse Calling System
Deployed at
Critical calls that never miss - even through reinforced walls.
Hospitals with deep wards, basement ICUs and reinforced shielding kept losing nurse call signals. We engineered a long-range RF stack with signal hopping that has become our reference design across the country's largest hospital chains.
The Challenge
Modern hospital architectures - thick masonry, basement floors, isolated ICUs, lead-lined imaging suites - aggressively attenuate RF. Standard nurse call radios drop packets, and the call simply does not reach the nurse station. In a critical-care setting, that is not acceptable.
What we engineered
- Long-range RF + signal hopping. Mesh-style hopping radios keep the call alive across any number of intermediate nodes - signal cannot get trapped on one path.
- RF boosters for shielded zones. Dedicated boosters cover MRI suites, basement ICUs and other RF-hostile environments.
- Nurse-station displays for clinical workflows. Beyond patient calls, the same display surfaces medicine alerts, dietary schedules and shift handover notes.
- Custom dashboards & analytics. Per-ward response times, average time-to-acknowledge, missed-call audit - built to match each hospital's QA process.
- Battery-operated handheld switches. Built for sites without UPS backup - patients hold the wireless switch and call from anywhere. Originally engineered for Siddaganga Hospital (Tumkur), now also at Kshemavana and widely used in old-age homes and senior-living facilities.
Key innovation
25+ years of fieldwork went into our current RF hopping firmware. Signal does not get lost - even in the toughest hospital architectures we've encountered.
GPS Digital Clock

GPS Digital Clock
Deployed at
Synchronized time - GPS, ethernet, RTC, indoor or outdoor.
Deep industrial facilities have no clean GPS sky view. Outdoor production yards demand water- and dust-proof hardware. Toyota wanted custom three- and four-sided hanging clocks. So we engineered a clock family for every environment.
The Challenge
Large pharmaceutical and manufacturing campuses sit deep inside reinforced buildings where GPS signal does not penetrate. Outdoor displays need IP-rated enclosures. And global IT campuses want time-zone walls and unconventional form factors - none of which a single off-the-shelf clock can deliver.
What we engineered
- Labour-room / Time-of-Birth clocks. HH:MM:SS GPS-synchronised clocks installed in delivery rooms, OTs and NICUs across Bengaluru maternity hospitals. Birth certificates legally require second-precision time of birth — these clocks eliminate any dispute over timing.
- Pharma cleanroom clocks (SS 304). Stainless-steel 304-grade, flush-mount, IP65 washable front-plate clocks for sterile manufacturing — FDA / GMP / ISO cleanroom compliant.
- Ethernet (NTP) clocks. Plug an ethernet cable in and the clock syncs from the network - perfect for GPS-shielded interiors and multi-time-zone walls.
- RTC standalone clocks. Built-in real-time-clock with crystal-backed accuracy for sites with neither GPS nor LAN.
- IP-rated outdoor variants + P10 LED. Dust-resistant, splash-resistant and fully waterproof builds (IP54 / IP65 / IP66) for outdoor production yards and gatehouses, plus high-brightness P10 LED for direct-sunlight readability.
- Master-Slave synchronised systems. Central GPS Master Clock distributing time over RS-485 to dozens of slaves — for railway stations, airports, hospital campuses and large multi-building sites.
- Custom form factors. Three-sided and four-sided suspended hanging clocks engineered specifically for Toyota's shop-floor.
Key innovation
One clock platform, every environment — GPS, NTP, RTC, master-slave, indoor, outdoor, cleanroom-grade, single-face, three-sided, four-sided. We build to the site, not the catalogue. The most demanding use case is the labour room: birth certificates legally require second-precision time, and these clocks settle that question.
Forex / Gold / Pricing Displays

Forex / Gold / Pricing Displays
Deployed at
Change a rate once. Every branch updates instantly.
Forex desks, jewellers and food courts were updating prices branch-by-branch - manually, with predictable lag and errors. We built a centralized display network where one head-office change pushes to every connected screen in seconds, plus an internet-fed mode that pulls live forex and bullion rates directly from market feeds.
The Challenge
A multi-branch operator - a bank with forex counters, a jewellery chain or a quick-service food court - has to keep prices identical across locations. Sending PDFs and asking branch staff to retype rates is slow, error-prone and looks unprofessional on the floor.
What we engineered
- Head-office controller. One operator updates rates centrally. All linked branches reflect the change in seconds.
- Internet-fed live mode. Boards pull forex, gold and silver rates directly from market data feeds - zero manual entry.
- LED and LCD form factors. High-contrast LED for outdoor and large halls; LCD for indoor counters where colour and layout matter.
- Multi-product layouts. Same controller drives interest-rate boards, bullion rates, locker info, restaurant pricing and food-counter menus.
Key innovation
A single source of truth for branch pricing. Every screen across the network stays in lock-step with the head office or the market feed.
