Abstract:
A method for controlling loop bandwidth of a phase locked loop is described. The method includes setting the loop bandwidth to a value, calculating at least one of a phase error and a frequency change that occur subsequent to any setting or adjusting of loop bandwidth, and adjusting the loop bandwidth based on at least one of the phase error and the frequency change
Abstract:
A method, apparatus, and computer instructions for broadcasting information. A change in data used by a number of processors in the data processing system is identified. A message is sent to the number of processors in the data processing system in which the message is sent with a priority level equal to a set of routines that use the data in response to identifying the change. This message is responded to only when the recipient is at an interrupt priority less favored than the priority of the message. A flag is set for each of the number of processors to form a plurality of set flags for the message in which the plurality of set flags are located in memory locations used by the number of processors in which the plurality of set flags remains set until a response is made to the message.
Abstract:
A continuity testing device has a probe element for contacting a conductor. A continuity testing circuit is coupled to the probe element. The continuity testing circuit will indicate continuity when a resistance level below a predetermined set-point is monitored. The continuity testing circuit has at least one of a vibrating or audible sensor to indicate electrical continuity of the conductor. The vibrating and/or audible sensor indicates a strength of the resistance level of the circuit tested by a quality of vibration or sound from the vibrating and/or audible sensor. A grounding wire is coupled to the continuity testing circuit. The grounding wire has a magnetic contact coupled thereto to ground the continuity testing device to any ferrous metallic grounded element. A housing is provided for holding and storing the probe element and the continuity testing circuit.

Abstract:
A curable flux composition is provided, comprising, as initial components: a resin component having at least two oxirane groups per molecule; a carboxylic acid; a fluxing agent represented by formula I: wherein R1, R2, R3 and R4 are independently selected from a hydrogen, a substituted C1-80 alkyl group, an unsubstituted C1-80 alkyl group, a substituted C7-80 arylalkyl group and an unsubstituted C7-80 arylalkyl group; and wherein zero to three of R1, R2, R3 and R4 is(are) a hydrogen; and, optionally, a curing agent. Also provided is a method of soldering an electrical contact using the curable flux composition.
Abstract:
Embodiments of the disclosed invention provide a user customizable monitoring system. For example, in one embodiment, the user customizable monitoring system includes a set of user-programmable portable sensors and a communication hub for enabling a user to customize features associated with the set of user-programmable portable sensors. In one embodiment, the communication hub is further configured to receive data from the set of user programmable portable sensors and perform a user specified action based on the received data. In some embodiments, a user selects any desired combination of different types of user-programmable portable sensors that come preconfigured to operate with the communication hub. Additionally, in some embodiments, a user may configure particular parameters associated with a user-programmable portable sensor using the communication hub.
Abstract:
A roof bar (10) for a motor vehicle (1) is disclosed in which an elongate load carrying member (313) is selectively held in a deployed position by a latch mechanism (320). The latch mechanism (320) interacts directly with the elongate load carrying member (313) and no separate stay is required to hold the elongate load carrying member (313) in the deployed position. The components (311, 315, 316) forming the roof bar (10) are all relatively thin when the roof bar (10) is in the stowed state, so as to minimize any change in vehicle height.
Abstract:
A system and method of allocating contiguous real memory in a data processing system. A memory controller within system memory receives a request from a data processing system component for a contiguous block of memory during operation of the data processing system. In response to receiving the request, the memory controller selects a candidate contiguous block of memory. Then, after temporarily restricting access to the candidate contiguous block of memory, the memory controller identifies a set of frames currently in use within the candidate contiguous block of memory, relocates the set of frames, and allocates the candidate block of memory for exclusive use by the requesting data processing component. The allocation of contiguous real memory occurs dynamically during the operation of the data processing system.
Abstract:
A motor vehicle is disclosed having one or more seat assemblies each of which has an automatically stowable head restraint associated with it. Each head restraint is pivotally supported by a stowable rear roof panel and is biased into a stowed position in which it lies adjacent to the rear roof panel by a spring. A latch mechanism is used to hold the head restraint in a lowered position in which it depends downwardly from the roof panel for use by an occupant of the motor vehicle. The latch mechanism is automatically released by the process of stowing the rear roof panel or a front roof panel.
