Patent number: 9947196Abstract: An asset tracking system that utilizes a wireless network system and has primary (main) and secondary (sub) tracking devices or ‘tags’ that are assigned to assets. The main tracking device acts as a coordinator and the sub tracking devices surrounding the coordinator act as end-devices. Each main device acts as a gateway network to long range communication while each sub device can only communicate in proximity profile (short range or nearby communication). Each sub device can communicate only with a main device. The main device passes data from the sub device to a remote host transparently. Each sub device sends its data when it triggered by a ‘ping’ from the main device.Type: GrantFiled: April 28, 2016Date of Patent: April 17, 2018Assignee: Senaya, Inc.Inventors: Brian Lee, Jahangir Nakra, Dadi Setiadi, Jamshed Dubash

Patent number: 9813850Abstract: An asset tracking system that utilizes a wireless network system and which includes primary (active) and secondary (passive) tracking devices. The primary tracking device acts as a coordinator and the secondary devices surrounding the coordinator act as end-devices. Each secondary device can communicate only with the primary device. The primary device passes messages (data) from the secondary devices to the remote host transparently. Each secondary device only sends its data when it triggered by a ‘ping’ from the primary device. When a ping event occurs, the primary device broadcasts a main data packet, in some embodiments followed by two additional data packets. Within this time span of the primary data packet, the secondary devices send their data packets to the primary device, in some embodiments, as two small data packets.Type: GrantFiled: April 9, 2014Date of Patent: November 7, 2017Assignee: Senaya, Inc.Inventors: Brian Lee, Jamshed Dubash, Jahangir Nakra, Dadi Setiadi

Patent number: 9523775Abstract: An RF asset-tracking device that has an extended operational life, thus increasing the duration between battery replacement or maintenance. The asset-tracking device is provided with an electro-mechanical energy-harvesting device to supplement the battery. The energy-harvesting device provides additional power to augment the battery on a temporary basis, when the battery level is low, until the battery can be replaced. In one particular embodiment, the tracking device has a power management system, a battery power source and a battery monitor, and an electro-mechanical energy-harvesting device and a high capacity supercapacitor operably connected to the power management system.Type: GrantFiled: February 26, 2014Date of Patent: December 20, 2016Assignee: Senaya, Inc.Inventors: Mrinmoy Chakraborty, Dadi Setiadi, Brian Lee, Jamshed Dubash, Jahangir Nakra
