Abstract:
A memory/storage module is provided that implements a solid state drive compatible with Serial Advanced Technology Attachment (SATA) or Serial Attached SCSI (SAS) signaling on a double-data-rate compatible socket. A detachable daughter card may be coupled to the memory module for converting a memory bus voltage to a second voltage for memory devices on the memory module. Additionally, a hybrid memory bus on a host system is provided that supports either DDR-compatible memory modules and/or SATA/SAS- compatible memory modules. In one example, the memory/storage module couples to a first bus (DDR3 compatible socket) to obtain voltage and/or other signals, but uses a second bus for data transfers. In another example, the memory module may repurpose/reuse electrical paths that typically carry non-data signals for data traffic to/from the memory/storage module. Such data traffic for the memory/storage module permits concurrent data traffic for other memory modules on the same memory bus.
Abstract:
A radio frequency identification (RFID) tag is coupled to a circuit board to track the specific operating and environmental conditions of each manufacturing stage as the circuit board passes through the manufacturing stages. An RFID reader and data collector are used at each stage to read the RFID tag and store its identifying information along with processing information, operating conditions, and results for each stage. This permits to quickly and accurately collect manufacturing information for each circuit board at various manufacturing stages as well as the operating conditions for each stage at a particular time. Such manufacturing metrics can then be retrieved on a stage-by-stage basis for a particular circuit board by an identifier printed on the circuit board.
Abstract:
A base station system and method for base station heat dissipation using chimneys where the base station system comprises a first structure, an enclosure, and a chimney. The first structure supports base station circuitry that generates heat. The enclosure encloses the first structure and the base station circuitry and forms an internal space. The chimney comprises a second structure forming dedicated space for heat dissipation. The chimney transfers the heat generated by the base station circuitry from the internal space to an external space outside the enclosure.

Abstract:
A technique for cooling an air flow through a heat exchanger device involves a controlled change of direction from an air input direction to cooling fins in the heat exchanger device. The heat exchanger device is angled relative to the air stream input direction. The heat exchanger device may include a fluid-carrying conduit, a plurality of sets of cooling fins coupled along the fluid-carrying conduit, and a plurality of air stream deflectors, coupled to the fluid- carrying conduit, that form dividers between the sets of cooling fins. In operation, the air stream deflectors may change in a controlled manner air stream direction from the air stream input direction into a direction approximately parallel with the cooling fins and, after passing out of the cooling fins, change in a controlled manner air stream direction to an air stream output direction.
Abstract:
Systems and methods for simultaneously partitioning a plurality of via structures into electrically isolated portions by using plating resist within a PCB stackup are disclosed. Such via structures are made by selectively depositing plating resist in one or more locations in a sub-composite structure. A plurality of sub-composite structures with plating resist deposited in varying locations are laminated to form a PCB stackup of a desired PCB design. Through-holes are drilled through the PCB stackup through conductive layers, dielelectric layers and through the plating resist. Thus, the PCB panel has multiple through-holes that can then be plated simultaneously by placing the PCB panel into a seed bath, followed by immersion in an electroless copper bath. Such partitioned vias increase wiring density and limit stub formation in via structures. Such partitioned vias allow a plurality of electrical signals to traverse each electrically isolated portion without interference from each other.

The system may include a touch screen display. Also, logic to process sales transactions may be included. The transaction terminal may include a cash drawer. The system authenticates users based on data from the sensor, and can regulate access, for example to a cash drawer, based on the authentication. Also described is a sensor module, security system, and method of operating a transaction terminal.
Abstract:
Improved systems and methods for laser trimming resistors printed on a substrate layer are provided. An exemplary embodiment measures a resistance value for each annular resistor and sorts the annular resistors into one or more bins based on the measured resistance values and target resistance values associated with each resistor. A laser trim file may then be assigned to each bin based on a predictive trim formulation, where each laser trim file defines a set of configuration parameters for a laser drill to conform each resistor with their respective target value. The laser drill uses the laser trim files to trim the resistors within each bin in accordance with the laser trim file assigned to that bin.

Abstract:
A built-in dual purpose interposer device for a data storage device carrier mechanism is provided. The interposer device may fill empty or voided space in the carrier mechanism created when a data storage device is changed between a "direct plug" position, or first configuration, and an "interposer" position, or second configuration. The interposer device may be changed back and forth between the first and second configuration multiple times. When in the first configuration, the interposer device may provide structural support to a front end of the carrier mechanism and when in the second configuration, the interposer device may provide an internal mounting base for the data storage device at the base or bottom end of the carrier mechanism. The ability to interchange the interposer device may provide for a built-in base for attaching the interposer device without having to add in additional parts or costs.
