International Classification:
G06F 13/00, G06F 13/14
US Classification:
710110, 710100, 710105, 710305
Abstract:
An apparatus, system, and method are disclosed for resetting an inter-integrated circuit (I2C) bus slave. A data line resistor in series is provided with a data line of an I2C bus in communication with the I2C bus slave. A clock line resistor in series is provided with a clock line of the I2C bus. A data line differential amplifier detects a first specified voltage across the data line resistor and a clock line differential amplifier detects a second specified voltage across the clock line resistor wherein the first specified voltage is substantially equal to a data line resistor resistance multiplied by a specified current and the second specified voltage is substantially equal to a clock line resistor resistance multiplied by the specified current. A time module detects the first and second specified voltage for a specified time interval. A reset module resets the I2C bus slave in response detecting the first and second specified voltage for the specified time interval.

International Classification:
G06F 13/00, G06F 13/14
US Classification:
710110, 710305
Abstract:
An apparatus, system, and method are disclosed for resetting an inter-integrated circuit (I2C) data line with negative voltage. A hang detection module detects an I2C hung line selected from a data line and a clock line wherein an I2C bus master and I2C bus slave communicate over the data line and the clock line. In response to the detected hung line, a negative voltage generator drives the data line to a specified negative voltage for a specified time interval. A clamp diode clamps the voltage of the data line to greater than a specified limit. On receiving the specified negative voltage, a voltage detector module detects the specified negative voltage of the data line. A timer module detects the specified negative voltage for the specified time interval. In response to detecting the specified negative voltage for the specified time interval, a reset module resets the I2C bus slave.

Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G06F 3/00
US Classification:
710 10, 710 8
Abstract:
A mechanism is provided for storage enclosures to communicate with one another using pre-existing cables allowing the user to dynamically attach different types and speeds of Fiber Channel enclosures together. The mechanism uses a transmit disable line and receive loss of signal line of a small form-factor pluggable optical cable to provide a communication link between enclosures before the Fiber Channel loop is setup and stable. The mechanism on the transmit side pulses the transmit disable line to communicate configuration information. The mechanism on the receive side receives the configuration information on the receive loss of signal line. The transmit disable line and the receive loss of signal line operate as a one-wire communication scheme, providing a communication link to communicate configuration information before the Fiber Channel loop is established.

Abstract:
A method, system, and computer program product are provided for communicating to a powered element in a rack system. A controller injects communication data onto power lines that provides power to a plurality of powered elements. The powered elements determine if the communication data transmitted via the power lines should be used for configuration using an address embedded within the communication data. The powered elements compare an embedded target address within the communication data to the address of the particular element. If there is a match between the addresses, the corresponding powered element processes the communication data to configure the powered element. As a result, data may be communicated over the power lines thereby eliminating the need for separate communication lines. Thus, the amount of cables required to interconnect the powered elements of the distributed data processing system may be reduced by eliminating the communication lines from the system configuration.

US Classification:
713501, 713400, 713500
Abstract:
An apparatus, system, and method are disclosed for resetting an inter-integrated circuit data line with a clock line. A hang module detects that a data line that carries data between an I2C bus master and an I2C bus slave is hung, wherein the I2C bus master and I2C bus slave communicate over the data line and a clock line that carries a clock signal. The clock module increases a clock line frequency to a specified frequency in response to the detected data line hang. The pulse generation module transmits specified clock pulses from the I2C bus master to the I2C bus slave over the clock line at the specified increased frequency in response to the detected data line hang. A frequency detector module detects clock pulses at the specified increased frequency. A timer module detects the specified clock pulses at the specified increased frequency. A reset module resets the I2C bus slave in response detecting the specified clock pulses.

The mechanism issues a request for data to a set of powered elements using a set of secondary communication channels in response to a reduction in a level of communications being detected. The set of secondary communication channels comprises one or more alternating current power lines and the request is sent as data injected onto the alternating current power lines to the set of powered elements. The mechanism receives the data using the set of secondary communication channels from the set of powered elements, analyzes the data to determine a set of recovery actions to restore the level of communications, and issues the set of recovery actions to the set of powered elements using the set of secondary communication channels.

Abstract:
Disclosed are discharge lamps for use in tanning applications and methods of making the same. The lamps include, among other elements, an elongated vitreous tube which has an outer periphery and axially opposed first and second ends that define an axial length for the tube. A coating is applied on the interior of the tube for emitting ultraviolet radiation in tanning wavelengths when a voltage to the lamp. The coating is specifically formulated so that the ultraviolet radiation emitted from the lamp in a range of about 320 nm to about 340 nm is less than or equal to about 10 percent of the ultraviolet radiation emitted from the lamp in a range of about 280 nm to about 400 nm.
