  • Publication number: 20240068969
    Abstract: A sensor for determining a hydrogen concentration in a channel of a fuel cell system, having a sensor housing, a measuring chamber, wherein the measuring chamber is arranged in the sensor housing, and a measuring chamber channel, wherein the measuring chamber channel fluidically connects the measuring chamber to the environment of the sensor, wherein the sensor can be mounted in such a way that the measuring chamber diaphragm is located in the channel. A channel having a sensor of this type and a fuel cell system having a channel of said type.

  • Patent number: 9711715
    Abstract: Read-only (“RO”) data to be permanently imprinted in storage cells of a memory array are written to the memory array. One or more over-stress conditions such as heat, over-voltage, over-current and/or mechanical stress are then applied to the memory array or to individual storage cells within the memory array. The over-stress condition(s) act upon one or more state-determining elements of the storage cells to imprint the RO data. The over-stress condition permanently alters a value of a state-determining property of the state-determining element without incapacitating normal operation of the storage cell. The altered value of the state-determining property biases the cell according to the state of the RO data bit. The bias is detectable in the cell read-out signal. A pre-written ferroelectric random-access memory (“FRAM”) array is baked. Baking traps electric dipoles oriented in a direction corresponding to a state of the pre-written data and forms am RO data imprint.

  • Publication number: 20070081379
    Abstract: One embodiment provides a system to assist setting a state of a latch system. The system includes a latch system connected to a node, the latch system residing in one of a first state and a second state. A charge storage device is coupled to maintain the node at a first voltage according to an amount of stored charge. A write assist system is connected between the node and a second voltage. The write assist network is configured, when the node is selected, to discharge the charge storage device and to pull the node from the first voltage to a discharge voltage that is outside a range defined by the first voltage and the second voltage to facilitate setting the latch system to another of the first state and the second state.

  • Publication number: 20050192159
    Abstract: A modular harness assembly worn by a person during physical exercise or rehabilitation. The modular harness assembly includes a non-stretchable waist belt that is secured around the waist of the patient or user, and can be associated with one or more auxiliary, non-stretchable harness component that can easily be added or removed from the waist belt. The auxiliary harness components can include a shoulder harness, a thigh harness having a movable connection to the waist belt proximate the hip joint, and a pelvic harness. The modular harness assembly can be used in combination with a hoisting system such as a block and tackle pulley system that is mounted onto a rolling carriage and an overhead rail.

  • Publication number: 20050131464
    Abstract: A system and method for long-term monitoring of cardiac conditions such as arrhythmias is disclosed. The invention includes a pulse generator including means for sensing an arrhythmia. The pulse generator is coupled to at least one subcutaneous electrode or electrode array for providing electrical stimulation such as cardioversion/defibrillation shocks and/or pacing pulses. The electrical stimulation may be provided between multiple subcutaneous electrodes, or between one or more such electrodes and the housing of the pulse generator. In one embodiment, the pulse generator includes one or more electrodes that are isolated from the can. These electrodes may be used to sense cardiac signals.
