| 20090233467 | Circuit board connector assembly and method for assembling such an assembly - A circuit board connector assembly mounted in a housing and method of mounting are described. The assembly has orthogonal first and second circuit boards (CB). The CB has a CB connector containing a CB housing with CB electrical contacts. A flexible electrical link has a link connector mounted in a link connector housing with link electrical contacts. A resilient pad is mounted on a link connector housing and a flexible sheet is mounted to both the pad and the link. The sheet spans a length of the link. When the length of the link is substantially planar, the sheet provides a ramp tapering away from the pad. During mounting of the assembly in the housing, the CB connector is operatively coupled to the link connector thereby forming a first connector assembly, and an abutment edge of the second circuit board slidably engages the sheet thereby compressing the pad. | 09-17-2009 |

| 20090062726 | MEDICAL IMPLANT DETACHMENT SYSTEMS AND METHODS - An implant assembly comprises an elongated pusher member, and an implantable device (e.g., a vaso-occlusive device) mounted to the distal end of the pusher member. The implant assembly further comprises an electrolytically severable joint disposed on the pusher member, wherein the implantable device detaches from the pusher member when the severable joint is severed, and a return electrode carried by the distal end of the pusher member (e.g., a coil disposed about the pusher member) in proximity to, but electrically isolated from, the severable joint. The implant assembly further comprises a terminal carried by the proximal end of the pusher member in electrical communication with the severable joint. | 03-05-2009 |

| 20120098619 | N PORT FEEDING SYSTEM, AND PHASE SHIFTER AND DELAY DEVICE INCLUDED IN THE SAME - A feeding system for providing a power using metal patterns having ‘U’ shape is disclosed. A phase shifter as the feeding system includes a first substrate, a first pattern as a conductor disposed on the first substrate, a second substrate separated from the first substrate and a second pattern as a conductor disposed on the second substrate. Here, the first pattern is overlapped with the second pattern, and electrical length of overlapped part of the patterns changes in case of changing phase of an RF signal outputted from the phase shifter. | 04-26-2012 |

| 20100182175 | Current Sensing and Background Calibration to Match Two Resistor Ladders - In one embodiment, a first resistor ladder includes a first voltage across the first resistor ladder. A second resistor ladder includes a second voltage across the second resistor ladder. A third resistor ladder includes a third voltage across the third resistor ladder. The calibrator receives the first voltage and third voltage and adjusts a current through the third resistor ladder to adjust the third voltage based on the received first voltage and third voltage. A buffer is configured to provide buffering for the third resistor ladder from the second resistor ladder. The third voltage of the third resistor ladder is stable even though the second voltage of the second resistor ladder is changing. | 07-22-2010 |
| 20100182178 | Two-Step Subranging ADC Architecture - First and second track and hold stages track and store an input voltage for a sample of an analog input signal. A coarse reference ladder provides a plurality of coarse references. In one embodiment, the coarse reference ladder includes a first coarse reference and a second coarse reference ladder. A coarse ADC performs a first comparison of the input voltage and the plurality of coarse references and outputs a coarse output based on the first comparison. A switch matrix includes a plurality of switches and is configured to close a switch corresponding to a coarse reference based on the coarse output. A fine reference ladder provides a plurality of fine references. A fine ADC performs a second comparison of the input voltage and the plurality of fine references and outputs a fine output based on the second comparison. Logic outputs a digital output for the sample of the analog input signal based on the coarse output and the fine output. | 07-22-2010 |
| 20100182183 | Reference Pre-Charging for Two-Step Subranging ADC Architecture - A coarse reference ladder provides a plurality of coarse references. A coarse ADC receives an input voltage. The coarse ADC performs a first comparison of the input voltage and the plurality of coarse references and outputs a coarse output. A switch matrix is configured to close a switch based on the coarse output. An input line corresponding to a coarse reference is coupled to the switch matrix. The input line is precharged to the input voltage. The input line settles from the precharged input voltage to the coarse reference. A fine reference ladder provides a plurality of fine references based on the coarse reference. A fine ADC receives the input voltage and performs a second comparison of the input voltage and the plurality of fine references and outputs a fine output. Logic outputs a digital output for the input voltage based on the coarse output and the fine output. | 07-22-2010 |
