摘要:
A side-mounted capacitor for a semiconductor die package is described. In one embodiment, a substrate has a die side to which an IC (integrated circuit) may be attached, and an edge adjacent the die side. A bypass capacitor is attached to the package substrate edge.

According to one aspect of the invention, an electronic assembly and a method for constructing an electronic assembly are provided. Insulating bodies interconnect a heat sink plate, or support plate, and a plurality of support members to form a heat sink assembly. The heat sink assembly is placed on a circuit board along with a semiconductor package. The entire circuit board is heated to solder the heat sink assembly and the semiconductor package to the circuit board. The insulating bodies thermally separate the heat sink plate and the support members so that heat is not conducted from the support members to the heat sink plate, and the heat sink plate and semiconductor package may be attached to the circuit board in a one-step heating process.
摘要:
A circuit board includes two planes. A via spans the planes, and an impedance component is placed in the via. The impedance component is coupled to both of the planes. The impedance component provides an impedance between the planes without the use of traces or hand soldering of components.

摘要:
A cap may be provided over the hinged cover of an integrated circuit socket to be surface mounted to a printed circuit board. The cap may protect the socket prior to the insertion of the integrated circuit. It may also facilitate the surface mounting of the socket to a printed circuit board. It may do so in at least two ways. The cap may facilitate convective heating by the provision of a series of openings in the cap. The cap may also be infrared transmissive so that infrared radiation from a surface mount oven passes through the cap to heat the socket. As a result, in some embodiments, better reflow is achieved and higher solder ball reliability may result.

A radio frequency identification (RFID) device may incorporate an existing feature on a substrate as an antenna. In some embodiments, the electromagnetic interference (EMI) guard ring on a substrate may form the antenna for the RFID device.
摘要:
A monitor, which may be closely associated with a handrail, may determine the amount of force applied to the handrail. The monitor may also determine the pattern in which force is applied to the handrail in order to assess how the user is contacting the handrail. The user's application of force to the handrail can be monitored along the course of movement along the handrail and may be compared to historical usage patterns.
摘要:
Briefly, in accordance with one or more embodiments, the location of a mobile device within a floor plan of a building or the like environment may be determined using a single transmission link between transceiver and the mobile device. A bit error rate value and a receiver signal strength indication value are measured for the present location of the mobile device in the floor plan. The coordinates where the mobile device is located may be determined by looking up the measured bit error rate value and the received signal strength indication value in a lookup table. Due to environmental factors of the floor plan, the combination of the bit error rate value and the received signal strength indication value corresponds to a unique coordinate location in the floor plan from which the location of the mobile device may be determined.
摘要:
A movement analysis system may use a force sensing mat to record a pattern of applied force from the user's feet as the user undergoes a series of directed movements. The movements may be directed by the system through indicator lights in the mat and/or directions provided on a display screen. The user's response to these directions may be recorded and analyzed to derive indications of the best exercise regime based on the user's capabilities.
