Patent number: 10868416Abstract: An electronic protection circuit includes a resettable fuse such as a positive temperature coefficient (PTC) thermistor or polymer PTC device. The resettable fuse enters a high-resistance tripped state in response to an overcurrent condition. One or more electrically controllable switches are placed in series with the resettable fuse. A monitoring and control circuit monitors voltage across the resettable fuse and to opens the switches when the voltage is outside of a predetermined range. The switches can remain open after the overcurrent event is resolved in order to allow the resettable fuse time to reset.Type: GrantFiled: March 2, 2018Date of Patent: December 15, 2020Assignee: Sierra Wireless, Inc.Inventor: Raymond Li

Patent number: 10630445Abstract: The present invention provides methods and apparatuses for implementation of cyclic prefix (CP) and demodulation reference signal (DMRS) in 2 sub-carrier pi/2 binary phase shift keying (BPSK) modulation in a communication system. DMRS symbols are interleaved with data-carrying symbols and configured such that they are alternatingly transmitted on different ones of the two sub-carriers. When a DMRS symbol is transmitted on one sub-carrier, the other sub-carrier may be unused. In implementing CP, phase rotations may be applied to modulation symbols, such that each concurrently transmitted pair of symbols is subjected to a same phase rotation. The phase rotation can be derived based on an average frequency of the two (e.g. adjacent) sub-carriers in use. The phase rotations can be updated recursively, and the update multiplied by a scaling factor.Type: GrantFiled: January 16, 2019Date of Patent: April 21, 2020Assignee: SIERRA WIRELESS, INC.Inventors: Gustav Gerald Vos, Steven John Bennett

Patent number: 10111067Abstract: A method and apparatus for communicating system information and random access in a wireless communication system in an LTE system is provided. In some embodiments, a system information block (SIB) is transmitted in a configuration that is receivable by a limited-capability UE. The SIB may indicate a schedule of additional SIBs transmitted in the same configuration. The schedule may also be transmitted in another manner which is beyond capabilities of the UE to receive but within capabilities of full-capability UEs. Legacy SIB data may be spread between multiple new SIBs in this configuration. The configuration may include a limited transport block size and use of a limited number of physical resource blocks. Also provided is a Master Information Block (MIB) which indicates an extended System Frame Number count. Also provided is a means for communicating operating requirements from a UE by varying the timing and frequency of random access calls.Type: GrantFiled: April 7, 2016Date of Patent: October 23, 2018Assignee: SIERRA WIRELESS, INC.Inventors: Steven John Bennett, Gustav Gerald Vos

Patent number: 10051570Abstract: A method and apparatus for communicating system information in a wireless communication system is provided. The method comprises generating and sending by a base station, for example an eNB, a system information block (SIB) which includes at least one correlation enhancement bit. This SIB is received by the terminal, for example a MTC UE, and this SIB is subsequently correlated with a previously received SIB. Further, upon the correlation of the SIB and the previously received SIB, a determination is made whether the SIB has in fact changed. Upon determining if the SIB has changed, the terminal selects the correct SIB which is to be used for configuring communication with the base station.Type: GrantFiled: November 5, 2015Date of Patent: August 14, 2018Assignee: Sierra Wireless, Inc.Inventors: Gustav Gerald Vos, Steven John Bennett

Patent number: 10009831Abstract: A method and apparatus for communicating system information, such as SIBs, from a base station to a terminal in a wireless network such as an LTE network. The base station is configured to broadcast the system information in accordance with a standard which defines a range of allowable values for characteristics of the broadcast. A restricted range of values for the characteristics is defined as a strict subset of the range of allowable values, and repeated broadcasts of the system information are configured in accordance with the restricted range of values. The terminal uses knowledge of the restricted range of values to facilitate reception of multiple repetitions of the broadcast. The terminal then combines the multiple repetitions to facilitate recovery of the system information.Type: GrantFiled: April 25, 2014Date of Patent: June 26, 2018Assignee: Sierra Wireless, Inc.Inventor: Gustav Gerald Vos
