Patent number: 8767677Abstract: When at user equipment UE transitions between radio access technology cells, at the transition a timer for controlling when the UE is to send a periodic location registration is reset. This avoids the UE being implicitly detached when it is unable/blocked in the packet-switched PS domain from performing a RAU but would be able to perform a LU, particularly when the UE is in PS/CS modes 1 or 2. Five different embodiments are detailed: the LU timer T3212 is reset with a value of time remaining in a tracking area update TAU timer T3412; T3212 is reset with an initial value for T3212; the RAU timer T3312 is reset with a value of time remaining in the TAU timer T3412; and the T3212 or T3312 reset is conditional on a value of time remaining in a PS backoff timer T3346 exceeding the value of time remaining in the TAU T3412.Type: GrantFiled: September 25, 2013Date of Patent: July 1, 2014Assignee: Broadcom CorporationInventors: Marko Tapani Niemi, Hannu Petri Hietalahti

Patent number: 8765544Abstract: An apparatus is disclosed to increase a breakdown voltage of a semiconductor device. The semiconductor device includes an enhanced well region to effectively increase a voltage at which punch-through occurs when compared to a conventional semiconductor device. The enhanced well region includes a greater number of excess carriers when compared to a well region of the conventional semiconductor device. These larger number of excess carriers attract more carriers allowing more current to flow through a channel region of the semiconductor device before depleting the enhanced well region of the carriers. As a result, the semiconductor device may accommodate a greater voltage being applied to its drain region before the depletion region of the enhanced well region and a depletion region of a well region surrounding the drain region merge into a single depletion region.Type: GrantFiled: September 5, 2012Date of Patent: July 1, 2014Assignee: Broadcom CorporationInventor: Akira Ito

Patent number: 8768253Abstract: Synchronized UWB piconets for SOP (Simultaneously Operating Piconet) performance. A common backbone (either wired or wireless) is employed that provides a common CLK (clock signal) to all of the various PNCs (piconet coordinators) of various piconets that may operate within a sufficiently close region such that interference could undesirably occur. By providing a very reliable CLK signal from a common backbone to all of the PNCs of the various piconets operating within a substantially close proximity to one another, very precise synchronization may be ensured for all of the communications performed therein. The various piconets may then even operate using TDMA (Time Division Multiple Access)—whose performance would be substantially compromised without effective synchronization. In addition, combined TFC (time frequency code) and TDMA may also be employed to support the communications therein thereby providing even another degree of orthogonality that provided by TDMA alone.Type: GrantFiled: April 26, 2012Date of Patent: July 1, 2014Assignee: Broadcom CorporationInventors: Jeyhan Karaoguz, Eric J.
