摘要： A fuel cell system that employs a diode electrically coupled between bipolar plates in a fuel cell of a fuel cell stack for preventing the fuel cell between the plates from reversing its polarity. The diode is a thin-sheet p-n diode including doped semiconductor layers and has a thickness relative to the thickness of the MEA in the fuel cell so that the overall stack thickness does not increase. When the fuel cell is operating properly the diode does not conduct and all of the current through the fuel cell goes through the MEA. If the electric load on the stack increases to a level beyond the capability of the fuel cell, where the potential across the fuel cell goes significantly below zero, the diode will begin to conduct so that any current that cannot travel through the MEA with the cell voltage less than one negative forward diode voltage drop is able to go around the MEA through the diode.

摘要： A ferroelectric memory comprises a plurality of memory cells and circuitry to sense data thereof. Power supply decoupling circuitry may decouple supplies of the memory device during a portion of reading data. Additionally, ferroelectric domains of the memory cells may receive a series of polarization reversals to improve domain alignment and malleability. To drive reference cells of the memory with such polarization reversals, a multiplexer may be configured to swap a data bitline with a reference bitline so that reference cells may be accessed as regular data cells. While reading a ferroelectric memory, a self-timer circuit may monitor characteristics of the ferroelectric material and adjust an integration duration for a sense amplifier based on the monitored characteristics. A sampling-comparator may sample a signal related to the ferroelectric material at one instant, which may then be used subsequently thereafter by the self-timer circuit to influence an integration duration of the sense amplifier.

摘要： A ferroelectric memory device comprises a plurality of subarrays having a plurality of bitlines and a plurality of wordlines crossing over the bitlines. Ferroelectric material is disposed between the wordlines and the bitlines to define a ferroelectric cell at each crossing of the wordlines and bitlines. Each subarray further comprises left and right voltage converters disposed on opposite sides thereof, to drive respective first and second sets of wordlines within the subarray. A plurality of global wordlines are couple to the left and right voltage converters of each subarray and are configured to establish the drive levels for respective wordlines of the subarrays. A bitline multiplexer selectively couples the bitlines of a select subarray to a plurality of sense amplifiers.

摘要： The present invention is directed to an inflated interspinous spacer. The interspinous spacer is inserted into the interspinous space between adjacent spinous process in a deflated or unexpanded state, and is inflated or expanded with an injectable filler material. Upon inflation, the spacer preferably distracts the spinous processes and assumes a shape that retains the spacer in position and preferably mechanically locks with the spinous processes. The spacer includes two separate balloons configured to have different compressive modulus so that one balloon is softer and more deformable than the other balloon.

摘要： An interspinous process spacer is generally rectangular and may have an upper face that generally opposes a lower face, front and back sides that generally oppose each other, an end side, and a nose that generally opposes the end side. The spacer preferably has rounded edges between the upper face and the front, end, and back sides and between the lower face and the front, end, and back sides. The nose of the spacer is preferably asymmetrical and tapers integrally, distally, and inwardly from the first and second faces to form a generally pointed or rounded distal tip. A spacer may be inserted laterally into the interspinous space through a small, posterior midline incision, allowing the preservation of the supraspinous ligament. One or more spacers may be placed between spinous processes of adjacent vertebrae, and result in distraction of the spinous processes which may limit extension of the spine.
