Granted: 2008-07-29
Abstract: A method and apparatus to prevent system deadlock in a dispatch system by monitoring link activity is described. The dispatch system is comprised of a set of remote units (10, 20, 22) which communicate with each other by broadcasting one at a time to the group. A remote unit (10) communicates with the other remote units through at least one base station (44). A communications manager (40) grants a remote unit (10) to be the exclusive system talker upon request through the base station servicing the requesting remote unit (44). The base station (44) monitors a series of data from the remote unit designated as the system talker (10) to detect voice activity. The base station (44) sends a surrogate request to the communications manager (40) to relinquish the system talker privilege if the voice activity falls below a predetermined threshold.

Abstract: In the field of bandages it is known to provide a non-slip coating to one surface of a bandage. However, previous such bandages have suffered numerous disadvantages. The disclosure relates to a bandage (1) having a resiliently stretchable, no n- slip coating (3) applied to it in wavy lines extending along the length of the bandage (1 ). The non-slip coating is such as to provide slip resistance between the bandage ( 1) and human skin, to which the bandage (1) may be applied in a compressive manner. An advantageous feature of the invention is the use of a barb hook-type fastener (5, 13) the shear force of which acts in a plane approximately coinciding with that of the outer surface of the bandage (1), thereby reducing the tendency of the bandage to peel apart as a result of forces arising from the compressive application of the bandage to e.g. a hum an limb.

Title: Arrangements to detect and respond to disturbances in electrical power systems
Inventor: RUTA JOSEPH W
IPC: H02H3/44
Filed: 1999-08-16
Granted: 2009-05-26
Abstract: A control arrangement and method is provided for detecting and responding to disturbances in electrical power systems. In a preferred arrangement, an integration is initiated that is based on a comparison of actual voltage of a source and a reference voltage. When the integration exceeds a predetermined value, the source is considered unreliable. Also in a preferred arrangement, a determination is made as to whether or not the disturbance is a downstream fault condition. For example, this is useful for applications where a transfer is made from a first source to a second source when predetermined disturbances are detected. In this manner, the transfer of the load to a second source is avoided which would continue the supply of the downstream fault. Additionally, the arrangement distinguishes between various degrees of disturbances to permit appropriate response based on the severity and type of disturbance. For example, a first immediate response, i.e. without intentional delay, is provided for more severe disturbances while a second delayed response is provided for less severe disturbances. The control arrangements transfers the load to an alternate source of power via the use of a high- speed source-transfer switching system that both avoids undesirable current flow between sources and minimizes undesirable transfer delays.

Abstract: The present invention provides systems utilizing fiber optics for monitoring downhole parameters and the operation and conditions of downhole tools. In one system fiber optics sensors are placed in the wellbore to make distributed measurements for determining the fluid parameters including temperature, pressure, fluid flow, fluid constituents and chemical properties. Optical spectrometric sensors are employed for monitoring chemical properties in the wellbore and at the surface for chemical injection systems. Fiber optic sensors are utilized to determine formation properties including resistivity and acoustic properties compensated for temperature effects. Fiber optic sensors are used to monitor the operation and condition of downhole devices including electrical submersible pumps and flow control devices. In one embodiment, a common fluid line is used to monitor downhole parameters and to operate hydraulically-operated devices.  Fiber optic sensors are also deployed to monitor the physical condition of power lines supplying high electric power to downhole equipment.  A light cell disposed downhole is used to generate electric power in the wellbore, which is used to charge batteries.

Granted: 2006-01-17
Abstract: There is disclosed an absorbent article including: a surface structure having a liquid-permeable surface sheet located on a liquid-receiving side; a back sheet; and an absorbent core sandwiched between the surface structure and the back sheet. In an area including at least a centerline extending in a longitudinal direction of the absorbent article, the surface sheet is corrugated to form recesses and ridges extending in the longitudinal direction and alternating with each other in a transverse direction perpendicular to the longitudinal direction. The ridges are given an elastically shrinking function in the longitudinal direction at least at their crests or vicinities thereof so that the surface structure is formed into a curved shape. The surface structure thus curved can fit the shape of a crotch. Therefore, the liquid is hard to flow in the transverse direction to prevent the leakage.

Abstract: The heat exchanger includes a fin and tube assembly with increased heat transfer surface area positioned within a hollow chamber of a housing to provide effective heat transfer between a gas flowing within the hollow chamber and a fluid flowing in the fin and tube assembly. A fan is included to force a gas, such as air, to flow through the hollow chamber and through the fin and tube assembly. The fin and tube assembly comprises fluid conduits to direct the fluid through the heat exchanger, to prevent mixing with the gas, and to provide a heat transfer surface or pathway between the fluid and the gas. A heat transfer element is provided in the fin and tube assembly to provide extended heat transfer surfaces for the fluid conduits. The heat transfer element is corrugated to form fins between alternating ridges and grooves that define flow channels for directing the gas flow. The fins are fabricated from a thin, heat conductive material containing numerous orifices or pores for transpiring the gas out of the flow channel. The grooves are closed or only partially open so that all or substantially all of the gas is transpired through the fins so that heat is exchanged on the front and back surfaces of the fins and also within the interior of the orifices, thereby significantly increasing the available the heat transfer surface of the heat exchanger. The transpired fins also increase heat transfer effectiveness of the heat exchanger by increasing the heat transfer coefficient by disrupting boundary layer development on the fins and by establishing other beneficial gas flow patterns, all at desirable pressure drops.
