Abstract: A holesaw system comprises a holesaw including a base and a generally cylindrical wall with a proximal end coupled to the base and a distal end with a cutting edge; a pilot drill bit including a front cutting tip, a rear shank portion, and an intermediate portion between the front cutting tip and the rear shank portion; and an arbor coupleable to the holesaw and to the pilot drill bit. The arbor is configured to be operable in a first mode in which the holesaw and the pilot drill bit are rotatable in unison to form a hole in a workpiece and in a second mode in which the pilot drill bit is rotatable independently of the holesaw to remove a plug of material from the holesaw.

Abstract: A detecting apparatus includes a multi-tier 3D integrated ASIC comprising one or more analog tiers and one or more digital tiers, and a sensor bonded to the multi-tier 3D integrated ASIC. The detecting apparatus includes an electrical substrate and a group of FPGAs or custom data management ASICs. The detecting apparatus also includes a thermal management system, a power distribution system and one or more connectors to transfer data to a data acquisition system configured for radiation spectroscopy or imaging with zero suppressed or full frame readout.

Abstract: A heat exchanger for transferring energy from a second fluid to a first fluid has a plurality of tubes to carry one of the fluids and a layer of thermal buffer members on one side of the tubes to act as a buffer to reduce high thermal stresses that may be caused by global temperature patterns and localized high gradients that occur in system transients such as start up and shutdown. Conventional heat exchangers often have a short lifespan due to high thermal stresses acting on the core of the heat exchanger. The heat exchanger uses the thermal buffer members as an increased thermal mass to cause the temperature of the heat exchanger core to change in a more gradual manner, thereby reducing thermal stresses.

Abstract: A processor-based system configured for searching in dynamically balanced trees is configured for linking the most often-searched elements of the tree to optimize search performance. Data elements include pointers for a tree-based index ordering and a doubly-linked list based index ordering. A background process links the most often-searched elements according to the linked list ordering and maintains the linked list ordering by first determining those elements having the highest importance values, defined as a number of times an element is successfully searched relative to aging or decay function. The linked list ordering is then arranged based on descending importance values. Each element also includes a go-to-tree flag, indicating to a search engine the point at which it is no longer beneficial to continue searching according to the doubly-linked list ordering.

Abstract: A transparently-bridged wide area network connecting Ethernet/IEEE 802.3-based local area networks uses redundant proxy devices on each LAN for internetwork communications. The proxy devices on a given LAN, implemented as data link switching (DLSw) devices, identify amongst each other a master proxy device for mediating services to be provided to an end station on the local area network. Each proxy device connected to the local area network sends a request to the identified master proxy device in response to detecting a frame transmitted by an end station on the local area network, for permission to establish a circuit connection for transfer of the frame via a wide area network. The master proxy device, based on prescribed criteria, selects one of the proxy devices for transferring the frame, and sends a grant response to the selected proxy device.
