Abstract: A test access port (TAP) controls monitoring and testing of static current IDDQ in integrated circuit (IC) devices having both a TAP of the type specified in IEEE Standard 1149.1 Test Access Port and Boundary Architecture and built-in current (BIC) monitors. BIC monitors are coupled between MOS or CMOS modules of the IC device and the low potential power rail (GND) for monitoring static current IDDQ. Bypass or shunt MOS transistors (N1,N2, . . . , NN) are coupled with primary current paths in parallel with the respective BIC monitors between the CMOS circuit modules and low potential power rail (GND). The TAP data registers (TDR's) include a design specific BIC shunt control TDR (BICSC TDR) constructed for receiving a coded BIC monitor bypass code (BICBC) at the TDI pin. BICSC TDR outputs are coupled to control nodes of the respective MOS bypass transistors (N1,N2, . . . , NN) for controlling the conducting state of the bypass transistors according to the BICBC.

Abstract: A flexible material wall trimming tool (10) cuts flexible material (32) such as flexible flooring material and flexible wall cove material at the intersection of a floor (34) and a wall (35). An elongate low profile block body (12) is formed with a bevel angle pusher surface (15) at the back end (14) of the block body (12) for pushing the wall trimming tool in the elongate cutting direction (18) using the palm of a hand. The bevel angle pusher surface (15) delivers force components downward against the floor (34) and sideways against the wall (35) for accurate cutting. A blade slot (20) is formed on the cutting side (28) of the block body (12) near the back end (14). The blade slot (20) is also formed at a compound angle. A blade holder (24) rigidly clamps a blade (22) in the blade slot (20) at the compound angle. A tool angle trim adjuster (42) is slidably received in a tool angle trim slot (40) on the opposite side (38) of the block body (12) from the cutting side (28).

Abstract: An output skew detection circuit detects and measures output skew tOSLH, tOSHL between multiple in phase common edge output signals propagated through a multiple signal driver circuit having n outputs. The output skew detection circuit senses common edge output skew across the n in phase output signals simultaneously and directly. A first logic gate has n inputs coupled to the n outputs, detects occurrence of either the first or last of the multiple common edge output signals, and generates a first skew detection edge signal at a first logic gate output. The first and last common edge output signals are the signals propagated with minimum and maximum propagation times tplhmin, tphlmin and tplhmax, tphlmax. A second logic gate has n inputs coupled to the n outputs in parallel with the first logic gate. The second logic gate detects occurrence of the other of the first and last of the multiple common edge output signals and generates a second skew detection edge signal at a second logic gate output.

The load rests on the floor of the vehicle bed and is restrained from shifting by the flexible fabric material panels. Flaps are formed at the top of respective sides of the elongate container and extend over surfaces of the sidewalls of the vehicle bed. Fasteners secure the flaps and elongate container to the sidewalls at desired locations along the vehicle bed. Typically, the flaps are secured to the upper surface of shelves formed along the sidewalls. Multiple elongate containers can be deployed.
