摘要:
A modular long bone prosthesis is provided having a proximal component and a retroversion component. The proximal component is configured at a proximal end to receive a head forming a portion of a joint and is formed at a distal end to mate with additional prosthesis components. The proximal component is formed to simulate an angle inherent in the proximal end of the bone to be replaced and includes an indicator adjacent the distal end to facilitate rotational alignment of the proximal component and additional prosthesis components. The retroversion component includes a proximal end configured to mate with the distal end of the proximal component. The proximal end includes alignment indicia for positioning relative to the indicator on the proximal component. When the indicator is in a first position relative to the alignment indicia the proximal component and the retroversion component establish a first alignment orientation forming an angle simulating the angle inherent in the proximal end of the right long bone of the long bone to be replaced. When the indicator is in a second position relative to the alignment indicia the proximal component and the retroversion component establish a second alignment orientation forming an angle simulating the angle inherent in the proximal end of the left long bone of the long bone to be replaced.
摘要:
A modular knee implant system allows a surgeon to select between several different styles of distal femoral implant components and several different styles of stem extensions while also allowing for use of a metaphyseal component. The metaphyseal component can be a universal one that is usable with all of the styles of distal femoral implant components through use of an adapter. A second adapter allows for use of stem extensions with different types of connectors with the metaphyseal component. A separate metaphyseal component could also be provided with a distal Morse taper post to mate with a distal femoral component having a proximal Morse taper bore. The metaphyseal component may have an outer surface that is configured to maximize contact area with the patient's bone, and may have a surface finish over a substantial part of its overall length that is conducive to bone ingrowth.
摘要:
Computer games deployed over communications networks such as the Internet are arranged with graphics rendering services to effect a real-time, automated fast rendering facility responsive to requests generated in view of game execution state. High-performance graphics authoring tools are used to produce graphics elements in agreement with a particular game design and scenario specification ‘on-the-fly’. These graphics are uploaded and stored in a database having a cooperating prescribed schema. A media player executing game logic is coupled to a render manager whereby render requests are passed thereto. The render manager forms scene files to be processed at a rendering application and finally to an assembler which converts all rendered graphics to a form usable at the media player. In this way, very high-quality real-time automated graphics generation is provided for bandwidth and memory limited platforms such as user workstations coupled to the Internet.

The present invention provides methods and apparatus for soil stabilization. First, a void is formed in the compromised soil strata. Then, an expandable member containing expandable materials is placed into the void. As the material expands to fill the void, the surrounding soil is compressed. This in situ compression if the soil increases the load bearing capacity and compressive strength of the soil. Additionally, the present invention provides a method for isolating the injected materials from the environment at the injection and/or polymerization point.
摘要:
An accessory for improved comfort and security of grasping of a handheld electronic device is disclosed. In a preferred embodiment, the accessory comprises TYVEK® material, or paper-like material made from synthetic fibers that has significant strength properties and repels water. The paper-like material is rolled to form a first loop that is configured to receive an index finger of a user. Also in a preferred embodiment, a second loop is formed to receive a middle finger. The accessory makes holding the electronic device easier and further a user has more freedom to operate the device with a thumb without losing secure grasp of the device. In yet a separate embodiment, the invention may be incorporated into an exterior protective case of the device.
摘要:
Methods and apparatus to detect content skipping by a consumer of a recorded program are disclosed. In a disclosed method, a plurality of recording times of sections of a recorded program are stored in association with playback times of the recorded program. Playback intervals between sequential pairs of the playback times are compared with corresponding recording intervals between sequential pairs of the recording times to determine if any portion of the recorded program was not played back in real time.
摘要:
An intelligent power management system that includes a circuit breaker containing a PLC module that spans open contacts of the circuit breaker to provide a communication path for PLC messages between the line and load sides of the circuit when the contacts are open. The contacts are motorized to permit remote operation through PLC messaging. Coupled to the PLC module is a controller, which controls the opening and closing of the motorized contacts under user control or via an adaptive load management algorithm that reduces peak power consumption and adapts a set of loads to changed power supply conditions. The controller can also dynamically alter operational current and fault threshold levels on a real-time basis based upon circuit requirements or environmental conditions. The algorithm runs a state machine and also manages loads in a limited power source environment such as when loads are powered by a generator.
摘要:
An independent automatic shedding system that automatically allows any combination of loads to powered under limited power availability (such as a standby power source) without overloading the generator or rewiring, while contributing to the stability of the power grid. A motorized disconnection actuation mechanism under control of a controller disconnects or recloses the contacts of a branch circuit breaker. A sensor detects the presence or absence of a power source and the type of power source, which is classified according to its type. A power source classification program is executed by the controller that interprets the sensor data and causes disconnection or reclosing of the disconnection actuation mechanism depending on a desired status (ON or OFF) of the branch circuit breaker when standby power is available. Conventional circuit protection is provided an optional advanced circuit protection such as ground or arc fault circuit interruption.
