Abstract: A user equipment (UE) establishes a unicast link with a second UE, including establishing an authentication and security establishment procedure between the first UE and the second UE. The UE establishes a security context with the second UE during the authentication and security establishment procedure. The UE starts a timer based on a status of the unicast link. The UE reestablishes the unicast link with the second UE using the security context when the unicast link is reestablished prior to expiration of the timer.

Abstract: A technique for receiving a DC or low frequency input signal using a chopper-stabilized amplifier includes chopping an input signal using a chopper clock signal to generate a chopped input signal. The input signal has a first voltage range and the chopper clock signal has a second voltage range. The chopper clock signal has peak-to-peak voltage over a period of the chopper clock signal. The peak-to-peak voltage is less than the first voltage range and is less than the second voltage range. A frequency of the input signal is at least an order of magnitude less than a frequency of the chopper clock signal. The second voltage range may be greater than or equal to the first voltage range. The technique may include generating a bias signal based on a voltage reference signal and an output signal having the first voltage range.

Abstract: Denim fabric, suitable for use as apparel, and garments made therefrom, wherein the denim fabric is made from at least about 50 wt % fibers produced from post-consumer recycled polyester and recycled cotton. In particular, warp yarns are made of recycled cotton and the other cotton, and the filling yarns are made of the post-consumer recycled polyester and spandex material. The warp yarn may be plied with like reclaimed warp yarn, and/or with virgin fiber warp yarn. The warp and filling yarns are combined to make the denim fabric. The denim fabric produced has strength and related properties sufficient for consumer use. The fabric or garment may also be subjected to washing, handwork, and/or other finishing effects that would change the look and feel of the fabric or add special characteristics.

Abstract: A removable storate container for a motor vehicle interior is disclosed. The storage container comprises first and second container halves and a hinge. The first container half has an indentation adapted to engage a projection on a floor of the vehicle. The second container half is disposed adjacent a side wall of the vehicle, and includes at least one hole adapted to removably engage a corresponding projection extending from a side wall of the vehicle. The hinge pivotably connects the first container half and the second container half. Optional features include foam padding disposed between the first container half and the second container half, and a handle connected to the storage container for carrying the storage container when the storage container is removed from the vehicle.
