摘要:
A virtual coatings application system has several features to enhance the realism of simulated spray painting. The system generally includes a display screen on which is defined a virtual surface (such as a truck door) that is intended to be virtually painted or coated by the user. The user operates an instrumented spray gun controller that outputs one or more signals representing data as to the status of the controls on the spray gun controller. The system also has a motion tracking system that tracks the position and orientation of the spray gun controller with respect to the virtual surface defined on the display screen. Simulation software generates virtual spray pattern data in response to at least the data from the spray gun controller and the position and orientation data received from the tracking system. Virtual spray pattern images are displayed in real time on the display screen in accordance with the accumulation of virtual spray pattern data at each location on the virtual surface.

A hands-free wireless wearable GPS enabled video camera and audio-video communications headset, mobile phone and personal media player, capable of real-time two-way and multi-feed wireless voice, data and audio-video streaming, telecommunications, and teleconferencing, coordinated applications, and shared functionality between one or more wirelessly networked headsets or other paired or networked wired or wireless devices and optimized device and data management over multiple wired and wireless network connections. The headset can operate in concert with one or more wired or wireless devices as a paired accessory, as an autonomous hands-free wide area, metro or local area and personal area wireless audio-video communications and multimedia device and/or as a wearable docking station, hot spot and wireless router supporting direct connect multi-device ad-hoc virtual private networking (VPN). The headset has built-in intelligence to choose amongst available network protocols while supporting a variety of onboard, and remote operational controls including a retractable monocular viewfinder display for real time hands-free viewing of captured or received video feed and a duplex data-streaming platform supporting multi-channel communications and optimized data management within the device, within a managed or autonomous federation of devices or other peer-to-peer network configuration.

My invention relates to heat engines. It has the following objectives: 1) Efficient conversion of any source of heat into useful mechanical power. 2) A novel proportional control valve system based on rotary refrigerant valves controlled by a programmable logic controller (PLC). This proportional valve system allows rapid response to any output power requirement. The PLC adjusts between energy supply and load requirements almost instantly. This also permits a servo mode implementation. 3) Uncontrolled runaway operation is impossible. Under adverse conditions, the system automatically de-powers. System integrity shall be maintained under all fault conditions unless an external force destroys the invention. 4) Internal heat storage inside the invention permits a slow rate of change for energy input. 5) The implementation of this invention provides for ease of construction from prototype to production of any size or scale. Nearly every part of this invention is composed of a round, rectangular or hexagonal flat plate, which can be easily machined or press-molded. The completed invention is comprised of a “stacked” configuration of these plates, which is then held together in slight compression by 4 (or 6) bolted studs at the corners. 6) The “working fluid” used inside this invention to convert heat into motion is a commonly available “non-ozone depleting” refrigerant. 7) The invention is comprised of a novel combination and arraignment of functional parts and details of construction, hereinafter illustrated and/or described. The device is a single cycle, short-cycle, four or six cylinder engine.

A method of friction stir welding and a non-consumable retractable shoulderless variable penetration friction stir welding tool. The tool includes a substantially cylindrical body portion, a head portion, and a tip section, each integral to the tool. The body portion has a longitudinal axis about which it is rotable, a diameter, a sidewall substantially parallel to the longitudinal axis, a proximal end, and a distal end. The head portion is located at the distal end of the body portion. The head portion has a base with a diameter substantially equal to the diameter of the body portion thereby forming a smooth transition between the body portion and the head portion, thus the tool has no shoulder. The head portion includes a face that converges to the tip section. The tool is retractable, reduces overheating, improves weld quality by reducing internal voids and lack of fusion, and facilitates variable penetration welds.

A host library controller employs a plurality of ports for establishing a plurality of communication paths from the host library controller to a medium changer library. The host library controller further employs a processor and a memory storing instructions for the processor to issue a command from a medium changer command set, and to select one or more of the ports for communicating the medium changer command to the medium changer library depending on a command processing status of each port.

An apparatus, system, and method are disclosed for automatically and transparently mapping tape drives within tape libraries to IP addresses. In one embodiment, the tape library includes, a DHCP server, a LAN to serial switch, and a library manager configured with the necessary modules to map the tape library devices to the proper IP addresses. The entire process may be transparent to users. The result is that the tape library is configured with the proper IP addressing without costly, time-consuming, and error-prone manual intervention. The tape library can be configured more quickly with accurate IP addressing and is able to operate efficiently and properly.

An orthopaedic screw is provided. The orthopaedic screw includes a shank defining an end and a periphery of the shank. A portion of the periphery defines a thread form The thread form includes a first flank, a crest adjacent the first flank and a second flank spaced from the first flank and adjacent the crest. The crest and the first flank form a first angle between the crest and the first flank. The crest and the second flank form a second angle between the crest and the second flank. The first angle and the second angle are different from each other.

A storage subsystem, method of testing storage media in the storage subsystem and program product therefor. The storage media, e.g., magnetic tape in a physical volume, is inserted into an input area in the storage subsystem, but not loaded into the subsystem library. The media input area on the physical volume is scanned and a test command is queued. The test storage media is moved to a drive for testing. After testing, the storage media is returned to the input area.
