Abstract: A universal press-fit connection allows a component having a connector pin to be connected to a compatible plated through hole of a circuit board regardless of circuit board thickness. The connector pin includes a proximate end adjacent the component, a distal end with a fork lock, and a compliant portion between the proximate and distal ends. A multi-width through hole includes a first portion partially extending through the circuit board and a second, wider portion extending beyond the first portion. The fork lock initially moves radially inward upon insertion into the first portion via flexing of the compliant portion, and re-expands when entering the second portion. The compliant portion engages the through hole and the fork lock secures the connector pin in the through hole.

Abstract: An electronic component is connected to a circuit board by forming a connector pin on the electronic component, the connector pin having a proximate end secured to the electronic component, a distal end with a fork lock, and a compliant portion between the proximate and distal ends. A multi-width through-hole is formed on a circuit board having a circuit board thickness greater than a length of the connector pin, with a first portion that is narrower than each of the compliant portion and the fork lock and extends partially through the circuit board and a second portion that extends beyond the first portion and is wider than the first portion. The connector pin is inserted into the first portion of the through-hole and the fork lock is moved beyond the first portion into the second portion of the through-hole.

Abstract: Optimizing an I2C bus frequency, the bus including signal lines coupling a master and slave nodes, a signal line coupled to a rise time detection circuit monitoring a voltage of the signal line, the voltage alternating between a logic low and logic high, where optimizing the frequency includes: detecting, during a rise in the signal line, a first voltage, the first voltage being greater than the logic low voltage; starting a counter to increment once for each clock period of the circuit; detecting a second voltage on the signal line, the second voltage greater than the first and less than the logic high; stopping the counter; calculating, in dependence upon the clock period and the counter value, a rise time; determining whether the rise time is greater than a maximum threshold; and increasing the I2C bus frequency if the calculated rise time is greater than the maximum threshold.

Abstract: Embodiments of the present invention provide a method, system and computer program product for telephone call co-processing in a mobile telephony environment. In an embodiment of the invention, a method of telephone call co-processing in a mobile telephony environment is provided. The method includes monitoring a resource state of a selected mobile telephone, such as cellular network signal strength or battery charge. The method additionally includes detecting weakness of the resource state sufficient to inhibit the maintenance of a telephone call in the selected mobile telephone. Finally, the method includes, in response to detecting weakness of the resource state, identifying a different mobile telephone proximate to the selected mobile telephone and utilizing the different mobile telephone to process a telephone call.

Abstract: In one embodiment, a memory module connector includes sidewalls extending along a length of the connector body. A longitudinally oriented socket is provided between the sidewalls for receiving a card edge of a memory module. A top of the connector defines a socket opening. A bottom of the connector is for mounting to a system board. A plurality of air deflectors is provided adjacent to the connector body to manipulate airflow to improve cooling. The size, positioning, and spacing of the air deflectors may be selected to optimize cooling.

Abstract: Selectively filtering incoming communications events in a communications device, including: receiving, by a communications event filtering module, an incoming communications event; determining, by the communications event filtering module, whether the communications device is currently servicing a call; responsive to determining that the communications device is currently servicing a call, determining, by the communications event filtering module, whether the call is interruptible; and responsive to determining that the call is not interruptible, blocking, by the communications event filtering module, the incoming communications event from presentation by the communications device until the call has ended.

Abstract: A hardware system comprises a master device and a slave device that are coupled by a signal line. A frequency generator in the master device places a selected frequency signal on the signal line. A frequency detector/comparator in the slave device, which is coupled to the signal line, determines whether the selected frequency signal on the signal line matches a predetermined frequency for the slave device. If the selected frequency signal matches the predetermined frequency, then a chip select node on the slave device is enabled, in order to permit a data exchange session between the master device and the slave device.
