Title: Leak detection apparatus using a mechanical float valve
Inventor: MALECZEK JOSEPH
IPC: F22D5/08
Filed: 2006-10-20
Abstract: A mechanical leak detection apparatus for use within a reservoir (3) at the base of a mains water fed water appliance. A mechanical float valve 6 is placed in the mains water supply line of the appliance. Should a leak occur, water collects in the reservoir (3) and the float valve mechanism 6 is used to shut off the water supply 1 to the appliance. A leak occurrence may activate a salt or fluorescent dye tablet 7 in the reservoir (3) which communicates that a leak has occurred through a clear window (4) in the front of the reservoir (3). Water and salt in the reservoir (3) may also activate a normally dormant 'sea battery' 8 which generates an electrical output 9 for use by optional external alarm circuitry. The apparatus may exist as a self-contained tray unit or can be built into newly manufactured appliances.

Title: Method and apparatus to facilitate macrodiversity reception
Inventor: CAI ZHIJUN
IPC: H04B7/02
Filed: 2007-04-23
Abstract: Separate Radio Network Controllers (11 and 13) exchange neighboring cell information between one another.

Title: A state-retaining output driver for an IC with power domains
Inventor: WANG BINGDA BRANDON
IPC: G06F1/32
Filed: 2008-10-13
Abstract: When the core 10 is powered down the output buffer 16 selectively outputs either (a) a retained and latched present logical state, which may be a high, a low, or a high-impedance state, or (b) an inactive logic state such as a high-impedance state. Power down of the core is sensed by circuit 24, which selectively asserts RTO to open the switches SW2,SW3 or asserts SNS to close SW1 under control of a mode bit stored in control latch 24. The signal RET can be asserted by a central controller, or generated locally following core power-up, to ensure output logic state retention when the core is powered down. The signal RET can be tied low if it is known at design stage that state retention will not be required. The buffer 16 may drive a signal outside the IC or may drive other domains within the IC. The buffer control circuit 22 may control several buffers. A central controller is not required to coordinate latching.

Title: Cascode level shifter transient protection
Inventor: DUBY JEAN-CLAUDE
IPC: H03K17/0812
Filed: 2009-04-20
Abstract: A cascode level shifter receives a low voltage input and generates an output in a high voltage range and is divided into low and high supply voltage sections, the combined voltage across which corresponds to the high voltage range. The level shifter comprises a driver switch 200,220 in series with a cascode switch 210,230 at a midpoint node that switches depending on the input and a reference voltage DVDD2. A perturbation circuit transiently varies the reference voltage in response to an input transition thereby turning the cascode switches on faster. The perturbation circuit can comprise an RC circuit having capacitors 240, 270 connecting the reference node to an input and resistors 250,260 that can be PMOS transistors (fig 3,.300,305); clamping transistors (fig 3, 320, 325) and cut-off capacitors (fig 3, 330,335). The reference voltage of a high voltage section cascoded switch (fig 5 400,420) can be perturbed by a pulling it down to ground with a switch such as an NMOS transistor (fig 5, 450). The pull-down switch can be operated by an exclusiveORcircuit (fig 7) that detects a transition. Dynamically varying the reference voltages reduces prevents VDS and VGS stress on the cascode switches and increases switching speed.
