Abstract: The invention provides a heat sink for flowing coolant into inlet manifold channels extending into a inlet edge of a manifold where the flow is forced downward into parallel and spaced micro-channels extending across the manifold channels and re-directing the coolant up into and out of outlet manifold channels extending into an outlet edge of the manifold and interleaved with the inlet manifold channels, and by maintaining a base-width of the micro-channels in the range of forty microns to one hundred microns, maintaining a base-height of the micro-channels in the range of two hundred microns to four hundred microns, maintaining a manifold-height through of the manifold channels in the range of one thousand microns to three thousand microns, and maintaining a manifold-width of the manifold channels in the range of three hundred and fifty microns to one thousand microns.

Abstract: A heat sink removes heat from an electronic device and comprises a base, a lid. An inner ring of first fins extend radially outwardly first length from an inner circle and extend axially a first height from the top surface of the base, and an outer ring of second fins extend radially inwardly a second length from an outer periphery and extend axially a second height from the top surface of the base. A confining plate extends radially above the fins and is spaced below the bottom surface of the lid whereby coolant fluid flows from an inlet opening of the lid through the center opening of the confining plate and radially outwardly through the fins and upward around the outer edge of the confining plate and into the space above the confining plate to an outlet opening. A nozzle having a throat is disposed above the lid and extends below the lid to the confining plate. A flow diverter extends upwardly from the top surface of the base and into and through the throat of the nozzle.

Abstract: Method and apparatus for detecting cargo state in a delivery vehicle. A method is provided for determining a cargo state in a delivery vehicle. The method includes sensing a cargo state change, and determining whether or not the delivery vehicle is in motion. The method also includes storing the cargo state change if it is determined that the delivery vehicle is not in motion.

Abstract: A fluid heat exchanger assembly cools an electronic device with a cooling fluid supplied from a heat extractor to an upper portion of a housing. A refrigerant is disposed in a lower portion of the housing for liquid-to-vapor transformation. A partition divides the upper portion of the housing from the lower portion and is flexible to vary the volume of the upper portion for modulating the flow of coolant fluid through the upper portion in response to heat transferred by an electronic device to the lower portion of the housing.

Abstract: A heat transfer assembly comprising of an electronic component attached to an attachment point located on a circuit board and a clamping mechanism which applies a downward force against a block. In return, the block applies force against a heat transfer device which contacts the electronic component. The interface between the block and the heat transfer device contain a number of tongues and grooves to allow for positive location of the block against the heat transfer device while the clamping mechanism is fastened to the support. The positive location is configured for applying a localized force against a specific area on the electronic component.

Abstract: A remote, electronic, mobile reporting module conserves wireless transmissions in its reporting to a monitoring facility. The time at which certain messages are sent is used to convey added information. Also, when coverage is unknown, the remote module incorporates data into a coverage query in order to save the need to subsequently transmit the data in the event the monitoring facility confirms coverage.

Abstract: A remote reporting unit, such as freight trailer monitoring device, generates a number of different status messages representing conditions such as door open, latitude, longitude, battery condition, and the like. The remote unit combines the status messages into an optimized output. Optimization is implemented by applying a predetermined mapping scheme to convert the status message's values into a consolidated output. Having optimized the message, the remote unit transmits the consolidated output in the form of a “feature code” such as a code prefixed by star (*) or another conventional prefix. Telephony equipment that receives the feature code via the cellular telephone network interprets the feature codes by reversing the re-mapping process.

Abstract: A portable air filtration system includes a filter housing having an air inlet and an air outlet. The filter housing defines a filtration chamber between the air inlet and the air outlet. The portable air filtration system uses an ionizing mechanism, a filter media, and an electrode to filter air. The ionizing mechanism ionizes particles within the air to a negative charge. The filter media is disposed between the ionizing mechanism and the air outlet for entrapping the particles. The electrode is disposed between the ionizing mechanism and the filter media to establish an electric field. The electric field is established between the ionizing mechanism and the electrode adjacent to the filter media. The electrode is also electrically-connected to ground and to the filter media for dissipating the negative charge of the particles entrapped within the filter media.

Abstract: A system for maintaining a distributed object system using a network. Data objects are maintained at a network controller and are each associated with a data object version sequence number (OVSN), indicating a state, version, or configuration of each data object. When a receiver transmits a message to the network controller, the message includes an OVSN, representing a state, version, or configuration of objects located at the receiver, so the network controller can interpret the message in accordance with the OVSN contained in the message. The network controller may update the receiver's data objects if necessary.
