The present invention relates to arrangement of devices, and, in particular doors, in the architecture of HVAC units.Where space is a consideration, having doors that are common and/or that can be used or nested in a common operative space, reduce the need of inventory of different parts, and allow for use of smaller interior HVAC space volumes in HVAC units.

A memory includes a first macro chip, a spine chip, and a common substrate. The common substrate is configured to pass signals between the first macro chip and the spine chip. The first macro chip, the spine chip, and the common substrate provide a memory.

Disclosed is a system for performing online data queries. The system for performing online data queries is a distributed computer system with a plurality of server nodes each fully redundant and capable of processing a user query request. Each server node includes a data query cache and other caches that may be used in performing data queries. The data query, as well as request allocation, is performed in accordance with an adaptive partitioning technique with a bias towards an initial partition...

A two axis (azimuth and elevation) stabilized common gimbal (SGC) for use on a wide variety of commercial vehicles and military vehicles which are employed in combat situations capable of stabilizing a payload of primary sensors and of mounting a secondary sensor payload that is independent of the moving axes. The SCG employs three gyroscopes, inertial angular rate feedback for providing gimbal control of two axes during slewing and stabilization. In addition the third (roll) gyroscope is used f...

A common rail diesel fuel injection system that uses as many as one high-pressure engine-cam-driven fuel pump per engine cylinder, each of the high-pressure engine-cam-driven fuel pumps being driven directly by the engine cam. The system includes a common rail to receive the outputs of the high-pressure engine-cam-driven fuel pumps to maintain a high and uniform fuel pressure. The system also includes a fuel transfer pump to supply relatively low-pressure fuel to the high-pressure engine-cam-dri...

Precision alignment of one or more parts on a common carrier is described. A self-aligned common carrier includes a carrier substrate having one or more pockets formed in the substrate. Each pocket includes a side profile formed in the pocket. A chip having an identical side profile that complements the side profile in the pocket is mounted to the carrier substrate by inserting the chip into the pocket. The complementary side profiles result in near perfect self-alignment between the chip and at...

A common mode filter includes a drum-shaped core 1 with a winding 2 and a plate-like core fixed to flanges 1b to form a closed magnetic path. Concave portions 4a are formed in at least one of facing potions of both cores to provide gaps between the flanges 1b of the drum-shaped core and the plate-like core 4. A plurality of electrodes 3 each of which is successive over a upper surface, end face and lower surface of each flange are provided at portions corresponding to the gaps in each flange 1b....

A common mode choke coil adapted for surface mount applications minimized in overall size (particularly in height), with an improved bonding coefficient. This common mode choke coil has a structure comprising a ferrite core consisting of a winding core and two square planar flanges with recesses formed therein, the square planar flanges being formed integrally on each end of a winding core thereof, a pair of external electrodes disposed on the square planar flanges, a plurality of windings wound...

An electrical machine, such as a router, switch, hub, etc., includes a housing in which a Primary Backplane and Secondary Backplane are mounted in stacked spaced relationship. A primary Bus is fabricated on the Primary Backplane and a secondary Bus is fabricated on the Secondary Backplane. Connectors with feed through elements provide mechanical support and electrical transmission between the Primary Backplane and Secondary Backplane.

A common mode signal attenuator includes a magnetic core, and a communications cable having at least one conductor adapted to transmit a communications signal. The communications cable is magnetically coupled to the core to form an inductive element having a magnetic flux path passing through the core. The inductive element has a volt-time capacity of at least about 0.0001 volt-seconds. An electrical transient suppression system includes an electronic device having a ground path, a communication...
