Publication number: 20130049765Abstract: An in-situ unplug detector circuit detects when a cable is disconnected or unplugged. Detection does not have to wait for normal signaling to pause, such at the end of a frame or timeout. Instead, detection occurs during normal signaling. When the cable is disconnected, the transmitter no longer drives the load at the far end of the cable, and thus can drive the near end to a higher high voltage and to a lower low voltage. The increased voltage swing is detected by a detector at the near end that amplifies the transmitter output to the cable. A fast detector has a higher bandwidth and faster response time than a slow detector, and generates a fast detect signal that crosses over a slow detect signal. When the cable is disconnected, the fast detect signal again crosses over the slow detect signal, and decision logic activates an unplug signal.Type: ApplicationFiled: August 25, 2011Publication date: February 28, 2013Applicant: PERICOM SEMICONDUCTOR CORP.Inventors: Hung-Yan Cheung, Michael Y.

Publication number: 20120286798Abstract: The present disclosure provides methods and devices for testing a connection between speakers and a power amplifier. The disclosed methods and devices solve a problem that, upon a connection test for a power amplifier which has a booster power source, when a midpoint potential of the power amplifier and the voltage of the speaker connection terminal are compared, and it is determined that short-circuiting occurs on a ground side when the potential of the speaker connection terminal is lower than the midpoint potential, a wrong test is conducted if a midpoint potential is higher than a battery voltage.Type: ApplicationFiled: March 27, 2012Publication date: November 15, 2012Inventors: Minoru Matsuyama, Taro Kitagawa

Patent number: 8299803Abstract: A monitoring system for connector pins exposed to conductive/corrosive fluids and/or corrosive environments includes a first sensing portion having a pin monitoring section configured to measure a pin current flow of at least one conductor pin, and transfer a first signal. A second sensing portion produces a second signal indicating by a contactless determination the presence of a fastener providing physical connection between an interface member and a component. A decision logic device receives the first and second signals, compares the pin current flow to a predetermined range of values, and isolates electrical power to the conductor pin when the first signal indicates the pin current flow is outside the predetermined range of values. A sensor body created of a non-ferrous material and connected to the component includes a first insert member having the conductor pin and a second insert member defining a sensor sensing proximal presence of the fastener.Type: GrantFiled: May 28, 2010Date of Patent: October 30, 2012Assignee: Harris CorporationInventors: Christopher D. Mackey, Scott E. Bartholomew, Duncan G. Harris

Patent number: 8294473Abstract: A cable detector includes one or more peak detectors that detect when a termination impedance is missing from the output of a line driver. A peak detection signal is asserted when signals on a transmission line exceed a threshold level. A fault condition is asserted when the peak detection signal is asserted for a sufficient length of time to indicate that an actual fault is detected. The time period required for detecting a lost or missing line termination is longer than the time periods for any one of the pathological conditions to avoid a false positive detection. After the peak detection signal is de-asserted, the fault condition will be maintained until another sufficient length of time has expired without a peak detection.Type: GrantFiled: April 14, 2009Date of Patent: October 23, 2012Assignee: Texas Instruments IncorporatedInventors: Robert Karl Butler, Vijaya Ceekala, Jim Wieser

Patent number: 8286010Abstract: A system includes a high-current junction, a voltage sensor, and a controller. Power connectors of two components are electrically connected at the high-current junction, where a high current passes between the two components at the high-current junction. The voltage sensor detects a voltage at the high-current junction. The controller performs a predetermined action in response to the voltage sensor detecting the voltage at the high-current junction being greater than a predetermined threshold voltage. The system may be a data center rack. The high-current junction may be the junction at which an alternating current (AC) input receives AC power from AC mains. The high-current junction may alternatively be the junction at which a power supply receives the AC power from the AC input to generate direct current (DC) power to provide to data center rack components insertable within the data center rack.Type: GrantFiled: November 9, 2009Date of Patent: October 9, 2012Assignee: International Business Machines CorporationInventors: Randhir S.

Publication number: 20120249159Abstract: A back end of the line (BEOL) fuse structure having a stack of vias. The stacking of vias leads to high aspect ratios making liner and seed coverage inside the vias poorer. The weakness of the liner and seed layers leads to a higher probability of electromigration (EM) failure. The fuse structure addresses failures due to poor liner and seed coverage. Design features permit determining where failures occur, determining the extent of the damaged region after fuse programming and preventing further propagation of the damaged dielectric region.Type: ApplicationFiled: March 29, 2011Publication date: October 4, 2012Applicant: International Business Machines CorporationInventors: Ronald G.

Patent number: 8278948Abstract: An electronic device has a chassis, and a printed wiring board (PWB) having a hole. A fastener is installed in the hole thereby securing the PWB to the chassis. A pair of conductive traces is formed in the PWB. A cap, being an amount of conductive glue, covers a part of the fastener and fills an electrically insulating gap between the two traces, to thereby form a conductive path that connects the two traces. A sensing circuit is coupled to the traces, to detect a change in impedance of the path and signal a tamper event alert. Other embodiments are also described and claimed.Type: GrantFiled: March 10, 2010Date of Patent: October 2, 2012Assignee: Apple Inc.Inventor: Timothy M. Johnson
