Abstract: A capacity counter system has a central capacity controller, a clicker to indicate when people enter or leave an area, and a video system for displaying a running count of how many people are in the area. The controller, clicker and video system communicate wirelessly using protocols that allow the controller to communicate with a plurality of clickers while being in close proximity to other controllers serving adjacent areas.

Abstract: Aspects of the disclosure relate generally to rack systems for housing computing devices. The rack may include shelves supported by flanges of a pair of corresponding inserts. The flanges may be spaced along the length of each of the inserts. The distance between the flanges may define the height of a shelf when placed in the rack. The pair of corresponding inserts may be placed along an inner sidewall of the rack by mating hooks of the inserts with corresponding slots of the inner sidewall and subsequently removed by demating the hooks and slots. For example, a pair of inserts with one distance between the flanges may be replaced by a pair of inserts with another distance between the flanges in order to increase the shelf height of the rack. By replacing the shelves and/or the inserts, a user may quickly and easily in order to reconfigure the rack.

Abstract: Aspects of the disclosure relate generally to rack systems for housing computing devices. The rack may include a plurality of removable shelves. A removable shelf may include a column having a plurality of slots. By stacking a plurality of the removable shelves in the rack, a larger column may be formed. This larger column may provide additional space to mount other features. In one example, the larger column may be used to mount a wire duct. The wire duct may be attached to a mounting plate having a plurality of hooks. The hooks of the mounting plate may mate with the slots of the columns of the shelves. The mounting plates may be used to mount features at other locations on the rack as well.

Abstract: Aspects of the disclosure relate generally to uninterruptible power supply units for systems requiring back up power. Each unit may include UPS circuitry for controlling charging and allowing discharging of a battery. The UPS circuitry may includes a controller and a plurality of metal-oxide semiconductor field effect transistors (“MOSFET”) switches. The MOSFETs may include charging and discharging MOSFETs arranged in series with the battery all driven by a single gate driver, such as a controller. In this regard, the controller may limit the charging current though all of the MOSFETs and charge the battery. The MOSFETs may be arranged such that if the charging MOSFET fails, the redundant charging MOSFET may continue to limit the charging current to the battery. Similarly, a redundant discharging MOSFET may be arranged in series with a discharging MOSFET in order to continue to provide discharging current if the discharging MOSFET fails.

Abstract: Aspects relate generally to hot swap control in uninterruptible power supply units for systems requiring backup power. A unit may include a pair of MOSFET switches configured as a bidirectional switch for battery charging and discharging current control. This configuration allows the unit to limit inrush current when the unit is connected to a DC power bus of a power system and also allows the unit to eliminate any current flow when it is disconnected. Upon insertion and extraction of the unit, the MOSFET switches are disabled to prevent any disturbances on the DC power bus. Hot swapping in the unit ensures that the overall power system, including the unit and the DC bus, operates reliably.

Abstract: Aspects of the disclosure relate generally to relates server rack architecture for housing computing components on a plurality of shelves. More specifically, the shelves of a particular rack may each include a power and data bus (“PDB”) pre-configured to support a particular number of devices of the shelf. A PDB may also include a number of power and data connections for blind mating with the devices of the shelf. The PDB may include two blades which extend away from the PDB and blind mate with the main bus bar. Thus, each PDB may route both power and data signals between a main bus bar for the rack and each of the devices of the shelf. A shelf may be reconfigured for a different number of devices by changing the configuration of the PDB.

Abstract: Aspects of the disclosure relate generally to a patch panel for networking components. The patch panel may facilitate access to the rear ports of the networking components. In one example, the patch panel may include a body and a face, and may mount to the networking component. Once mounted, one or more jumpers may be connected to rear ports on the component as well as connection interfaces mounted on the face of the patch panel. In this way, the rear ports may be accessible from the front of the component by the connection interfaces.

Abstract: A computer implemented method, data processing system, and computer usable code are provided for dynamically creating data capture elements. The aspects of the present invention receive a request for a data capture form and retrieve template build data for building the data capture form to form retrieved template build data in response to receiving the request. Using the retrieved template build data, a form definition is retrieved to form a retrieved form definition and data element definition is retrieved to form a retrieved data element definition. Using at least one of the retrieved template build data, the retrieved form definition, and the retrieved data element definition, a data capture form template is then created.

Abstract: An alignment system for use in connection with a patient handling system and a nuclear medicine gantry is provided. The alignment system includes a nuclear camera alignment fixture mountable to the nuclear detector. The nuclear camera alignment fixture includes a pair of lasers mounted in a known position relative to a center of the nuclear detector and oriented substantially toward the nuclear medicine gantry. The nuclear camera alignment fixture further includes a pair of laser targets provided on the nuclear medicine gantry. Each laser target has a fixed location with respect to an axis of rotation of the nuclear medicine gantry. The nuclear detector is moved relative to the nuclear medicine gantry until a laser beam from each laser hits a respective laser target. The alignment system is also capable of aligning the patient handling system with respect to the axis of rotation of the nuclear medicine gantry.

Abstract: Apparatus and methods for the generation of water in a direct oxidation fuel cell. Water, in addition to carbon dioxide and heat, is produced when carbonaceous fuel or fuel solution is oxidized in the presence of air and a suitable catalyst. This oxidation reaction is performed on a surface that allows for the introduction of oxygen in the presence of a catalyst. Water produced can then be directly added to the fuel solution thereby diluting the fuel solution to a desired concentration, or may be separately and then later added to fuel solution for the normal fuel cell operations depending on the permeability of the membrane to water.

Abstract: A talc dispenser for cue sticks in which a housing having a talc storage cavity is formed with a through tubular passageway configured to allow insertion of a cue stick shaft. A metering element is movable to cause talc to pass out of said storage cavity and into the enclosed space to thereafter be deposited on an inserted cue stick by rubbing contact with a tube of bristle material rolled up within the through passage and on which the talc is distributed. A chalk block holder is received in a housing recess and a housing holder has a belt clip for convenient storage of the dispenser.
