Patent number: 9865448Abstract: A light source, with electrodes of alternating polarity attached to a substrate in an excimer ultraviolet (UV) lamp, for generating a plasma discharge between each of the electrodes. The shape of the substrate can shape and control the plasma discharge to reduce exposure of materials susceptible to attack by the halogens. The electrodes can be located such that the plasma discharge occurs in a region where it produces less contact of the halogens with the vulnerable areas of the lamp enclosure. The materials, such as the electrodes, substrate, and envelope, can be selected to withstand corrosive materials. In another embodiment, a plurality of sealed tubes, at least some of which contain an excimer gas are positioned between two electrodes.Type: GrantFiled: January 30, 2015Date of Patent: January 9, 2018Assignee: Ultraviolet Sciences, Inc.Inventors: James Randall Cooper, Ronald W.

Patent number: 8547064Abstract: A battery cell tab monitoring apparatus includes a conductive element electrically connected between two battery cells. The conductive element is connected to a sensing circuit including a pull-down current source connected to pull current from the conductive element and/or a pull-up current source connected to drive current into the conductive element. A voltage measuring circuit is connected to sense voltages during operation of the pull-down current source and the pull-up current source to be used to determine the status of the conductive element. For instance, voltages beyond certain fixed or variable thresholds indicate that the conductive element is flexing or cracking, which can be a precursor to its breaking. Voltages beyond other fixed or variable thresholds indicate that the conductive element is fully disconnected. The current sources used to push and pull the sensing currents may be used to bring the battery cells into balance when an imbalance is detected.Type: GrantFiled: January 14, 2010Date of Patent: October 1, 2013Assignee: Texas Instruments IncorporatedInventors: J.

Patent number: 8541981Abstract: A control circuit of a battery power-path management circuit establishes a first power path between a battery input node and an output node when the input node voltage is larger than a charger input node voltage and a second power path between the charger input node and the output node when the voltage on the charger input node is larger than the battery input node voltage. It controls the second power path to provide power to the output node, enabling battery charging and protection over a battery voltage range from about zero volts. It has low power consumption and can support wide-swing power supply voltage from as low as one volt to as high as maximum allowed Vds of drain-extended devices. It can use smaller device sizes because the PMOS switch gate voltage is 0V when the power supply is not too high.Type: GrantFiled: November 10, 2010Date of Patent: September 24, 2013Assignee: Texas Instruments IncorporatedInventors: Weibiao Zhang, J.
