Pryme CheckPoint

Pryme CheckPoint is a real time location tracking software using Pryme’s proprietary GPS MIC.  The Pryme GPSMIC is a two-way radio microphone with built-in GPS receivers; the GPS location of each microphones are encoded and transmitted via the two-way radio band to the radio base station.  The software I created – Pryme CheckPoint – is a software that runs on the base station PC to interact with the microphones over the air.

Technical Feature Highlights

  • Used Singleton object to store software settings storage, for flexible access throughout the system
  • Created API interface to communicate with microphone via binary commands
  • Implemented offline Google Map feature – downloads google map tiles and store them offline, then reconstruct the map tiles and redirect google map’s javascript requests to pre-cached local locations

Pryme EZTraQ Location Logging Solution

The Pryme EZTraQ (I & II) was built based on the successful TripBook products.  In addition to the original trip logging and reporting features, it also features Photo Geotagging, GPS Trip Compare, Waypoints & Users Management.

GiSTEQ Guardian Real-time GPS Tracker – Part 2

Part 2 of Real-time tracker project is to build a PC tracking client application and a central Web Server application to handle user login credential and location histories.

Due to schedule concerns, after I have designed the Web Service interface and functional requirement, we have outsourced the web server application part to an outside programmer.  Meanwhile, I was designing and coding the PC tracking application.

  • Created a step-by-step setup wizard to help user create their online accounts, setup the tracker, and start using the applications
  • PC clients is capable of communicating with the GPS tracker via either GPRS or USB connection
  • Designed a synchronization mechanism to synchronize tracker location history between the location server and local databases
  • Integrated Google Map API for tracker location display

GiSTEQ Phototrackr

This is my very first commercial work project – and it’s being sold worldwide.  The main program was designed and coded from scratch using C++/CLR and C#; there is also a product activation module done using ASP.Net WebService.

Technical Features:

  • Geotag JPEG images by examing the image’s Exif properties and compare it against GPS positions collected by a dedicated hardware
  • Embed Google Map with Google Map API in the Windows application host
  • Interact between Google Map javascript and the host Windows application through custom events & delegates
  • Inter-op between native Windows API and .Net framework for communicating with GPS data logger hardware, including retrieve GPS data points collected by the device, and configure various recording settings on the hardware
  • Analyze GPS location points to determine discontinuity between GPS tracks
  • Reduce route drawing complexity and google map javascript loading time by using various line simplification and points reduction algorithm
  • Integrates various web services API for additional functions including reverse-geocode and photo upload with location data
  • Product activation modules coded using ASP.Net WebService
