Abstract: Various prison services are rendered more efficient by providing inmates access to portable electronic devices in a controlled and regulated manner. A dispenser is employed to control and monitor the checking out and return of portable electronic devices and to communicate with such devices during use by inmates to monitor inmate use and ensure the portable electronic devices are only used by inmates as authorized.

Abstract: An apparatus (300) for removing contaminant particles (205) from a component (202, 204) of an apparatus (140, MT), the contaminant particles giving rise to an ambient electric field (E), the apparatus comprising: a collection region (301) for attracting the particles, wherein the ambient electric field is at least between the component and the collection region; and an electric field generator configured to establish an applied electric field between the collection region and the component to cause the particles to be transported from the component to the collection region, wherein the electric field generator is configured to determine the polarity of the applied electric field based on the ambient electric field.

Abstract: The present invention relates to a coating on a substrate. It is an object of the present invention to provide an improved coating on a substrate, which coating is to reduce the temperature felt by a person walking on the substrate as well as the actual temperature on the surface. The present invention provides a coating on a substrate that includes an impregnation material, respectively base material, which is adhered on the substrate, a particulate material adhered on the impregnation material, respectively base material, and optionally, a top coat covering an upper surface of the coating, in which the particulate material consists of crushed acrylic paint and/or wherein the particulate material is a platelet-shaped particulate material, and/or wherein the particulate material has an angular or very-angular shape such that the upper surface of the coating has a roughness of between 0.5 mm and 3 mm.

Abstract: A method, system and article of manufacture for simulating latency between software applications. There is provided a middleware component, e.g., a delay driver, within a multi-tier software product, the middleware component driver enables simulation of both latency and bandwidth restrictions experienced by the components in the multi-tier software product. The middleware component determines whether I/O request packets should be delayed, selects the number and types of I/O requests packets to be delayed and the amount of time to delay processing of the packets. Through the use of such a middleware component, a user is able to simulate various conditions experienced by the multi-tier software product.

Abstract: A three-dimensional interactive book includes a wheelfold sandwiched between front and rear covers. The front cover has illustrations on both the convex and concave surfaces of a three-dimensionally contoured element. The rear cover has a holographic element. The wheelfold has a wheel rotatably mounted between opposite front and rear panels. Primary pictorial elements on the wheel are selectively visible through a window on the front panel. A secondary pictorial element on the front panel is juxtaposed with the window. Selected surfaces, elements, and panels have text written thereon.

Abstract: A drive system for a grounds care device using two identical final drives in combination with two identical power units to provide directional drive to the wheels. The final drives and power units are assembled to each other differently for use on each side to provide the required relative reverse rotation of each drive wheel while maintaining the same direction of control movement for forward (or reverse) movement of each drive wheel (in regards to machine movement). Additionally, the drive belt for the cutting unit is routed between the power units (rather than under or over) to allow a lower center of gravity for increased stability.

Abstract: A neutral biasing system is disclosed using a neutral biased biasing system on a control column to bias a remote power unit into a neutral condition.

Abstract: An implement lift mechanism for a grounds care device uses a lost motion interconnection between a rotary lift flange and an integral lift/connector link coaxial therewith to selectively control the height of the implement. The lost motion interconnection allows the implement to float upwards over uneven terrain. Additionally, a spring can be used to assist in aiding the implement and reducing lift force.

Abstract: A control for a lawn and garden vehicle, such control utilizing a "U" shaped main direction control pivotally mounted to the handlebars. The control being physically interconnected to a transmission such that movement of the direction control forward causes the vehicle to move forward, and movement of the direction control backward causes the vehicle to move in reverse with the control being spring biased into a central neutral position.

Abstract: A full flotation mower deck for a rear engine walk behind lawn mower, such flotation deck including a fixed frame having a pivoting axle, with the mower deck independently supported by anti-scalping wheels and interconnected to the frame by pins with a separate mechanical interconnection between the mower deck and the frame for forward and aft movement in respect thereto.

Abstract: The invention relates to a hypodermic syringe in which a hollow needle is surrounded by a protective sheathing in such a way that after the injection has been performed the protective sheathing encloses the tip of the hollow needle to provide protection.
