Abstract: A head mounted display system for displaying image content to a user comprises at least one display configured to be worn by a user to present virtual content to first and second eyes of a user, one or more inwardly facing sensors or camera configured to monitor one or both of the users eye and processing electronics. This head mounted display system is configured such that virtual content activity can be initiated and/or driven from eye inputs such as gaze direction, eyelid motions (e.g., blinking), and/or other eye gestures.

Abstract: The present invention provides a long-bladed bolster 1, comprising a substantially planar cutting body 2 having one edge formed as a blade 3 of sufficient length so that the blade 3 is arranged in use to be positioned substantially centrally on a concrete masonry unit (CMU) to enable the block to be divided without the bolster 1 requiring repositioning, the bolster having a striking body on a second long edge of the cutting body opposite to the cutting blade configured to receive repeated blows from a striking implement in use and to transmit these through the cutting body to the blade and the bolster having an integral handle that extends from the cutting body and/or striking body of the bolster substantially centrally along the length of the cutting body 2 and substantially orthogonally to the plane thereof.

Abstract: This disclosure provides marking implements for making radiopaque markings, and methods of using the same.

Abstract: A roofing ladder with a modular angularly adjustable platform facilitates roofing work by providing a platform assembly which can be adjusted angularly to provide a desired slope for sitting or standing on or for storing tools or supplies. A beam provides structural support. A roof anchor hook connected to the beam contacts the opposing roofing surface to hold the ladder in place. A wheel assembly allows a user to easily mount the ladder on a roof. A plurality of step rods laterally connected to the beam provides steps for climbing the ladder as well as attachment locations for the platform assembly. A plurality of beam lifters provides a means to lift the beam off the roof surface for performing work on the roof surface underneath the beam. An extension slot allows the ladder to be extended for longer roofs or more easily manipulated into place using an extension pole.

Abstract: Apparatus and methods for distributing print jobs. A print job is generated at an application node of a network, and has associated therewith print parameters. The print job is routed to a distribution node on the network. The parameters are then parsed from the generated print job and the print job parameterized with predetermined metrics that are a function of at least one of the parsed parameters. The parameterized print job is then routed to a destination device on a destination node on the network.

Abstract: A custom-moldable patellar support product for improved patella tracking in the femoral groove and relief of associated patella femoral pain syndrome, and including an outer container formed of moisture-impervious material and an initially-moldable, patellar support positioned in the container in substantially moisture-free conditions and sealed therein against entry of moisture until use. The support includes a substrate and a reactive system impregnated into or coated onto the substrate. The system remains stable when maintained in substantially moisture-free conditions and hardens upon exposure to moisture to form a rigid, self supporting structure. A flexible protective pad is positioned on one side of the substrate along its length to provide a cushioning barrier between the substrate and the skin of a patient when the patella support is in use. An outer cover covers the substrate on the side opposite the protective pad.

Abstract: An apparatus and method for facilitating an anonymous shipment, including a memory device for storing information regarding the identity and shipping address for at least one individual, a receiver for receiving an order for at least one of a good and a service, a processor for processing the order for the at least one of a good and a service, wherein the processor generates an order message, wherein the order message contains a shipping message containing at least one of an anonymous shipping address information, an encoded shipping address information, an encrypted shipping address information, and a disguised shipping address information, wherein the shipping message conceals the address of an individual who at least one of placed the order and is to receive the shipment, and a transmitter for transmitting the order message to a provider of at least one of goods and services for order fulfillment.

Abstract: With shrinking dimensions, and closely spaced runners, capacitive coupling between bitlines in dual port SRAMS becomes an important design issue. Techniques for reducing that coupling are described. A shielding runner placed between the read and write bitlines and tied to V.sub.DD or V.sub.SS substantially reduces unwanted crosstalk. Word lines can be similarly isolated.

Abstract: The specification describes interconnection layouts for chip-on-chip packages using solder bump interchip connections as vias between a single level metal interconnection pattern on the lower support IC chip and another single level interconnection pattern on the upper IC chip. This arrangement allows for the formation of air isolated crossovers of features on either chip.

Abstract: The invention is directed to a memory cell with a floating gate and a method for charging the floating gate using channel-initiated secondary electron injection (CISEI). In the device of the present invention, a positive bias voltage of about 1.1 volts to about 3.3 volts is applied between the drain and the source when introducing charge onto the floating gate. A negative bias voltage of about -0.5 volts or more negative is applied to the substrate and the source. The drain substrate bias induces a sufficient amount of secondary hot electrons to be formed with a sufficient amount of energy to overcome the energy barrier between the substrate and the floating gate to charge the floating gate.
