Abstract: A method, computer system, and a computer program product for augmented reality guidance are provided. Device orientation instructions may be displayed as augmented reality on a display screen of a device. The device may include a camera and may be portable. The display screen may show a view of an object. At least one additional instruction may be received that includes at least one word directing user interaction with the object. The at least one additional instruction may be displayed on the display screen of the device. The camera may capture an image of the object regarding the at least one additional instruction. The image may be input to a first machine learning model so that an output of the first machine learning model is generated. The output may be received from the first machine learning model. The output may be displayed on the display screen.

Abstract: Disclosed are apparatus and corresponding methodology for providing a blower attachment for a handheld drill. The blower attachment is configured to be secured over the chuck end of a drill and provides a drive shaft driven blower that may be conveniently employed to provide additional combustion air to an incipient fire. The drive shaft is secured in the drill chuck in a manner identical to that employed to secure ordinary drill bits. The blower housing may be constructed at least in part of elastomeric material to assist in attachment of the housing to the drill and to provide flexibility for air direction. An air exit port for the blower housing may be formed of heat resistant material.

Abstract: Under the present invention, a GUI is provided that allows an assembly line to be both graphically and dynamically configured. In general, the GUI allows a designer or the like to “graphically” configure: a hierarchy of categories representing the assembly line; the process points along the assembly line; the different events that can be triggered at the process points; the actions that are taken in response to the events; the processes (sequences of actions) for the events; and the input parameters for the events and the actions. In a typical embodiment, the GUI is maintained on a system that is separate from the central computer controlling the assembly line. This not only allows the assembly line to be configured remotely, but also without ceasing operation of the line.

Abstract: A global positioning satellite receiver having an antenna for receiving a L1 signal from a satellite. The L1 signal is processed by a preamplifer stage including a band pass filter and a low noise amplifier and output as a radio frequency (RF) signal. A mixer receives and de-spreads the RF signal in response to a pseudo-random noise code, i.e., Gold code, generated by an internal pseudo-random noise code generator. A microprocessor enters a code tracking loop, such that during the code tracking loop, it addresses the pseudo-random code generator to cause the pseudo-random code generator to sequentially output pseudo-random codes corresponding to satellite codes used to spread the L1 signal, until correlation occurs. When an output of the mixer is indicative of the occurrence of correlation between the RF signal and the generated pseudo-random codes, the microprocessor enters an operational state which slows the receiver code sequence to stay locked with the satellite cede sequence.

Abstract: A vehicle near obstacle detection system includes a plurality of radio frequency heads that can transmit and receive both frequency-modulated, continuous wave and two-frequency Doppler radar signals, such that the system operates in frequency-modulated, continuous wave radar mode and in two-frequency Doppler radar mode. The radio frequency heads used for transmitting the radar signals transmit their radar signals in accordance with commands from a system controller. The radio frequency heads are provided at various locations on the vehicle, directed at points around the vehicle which cannot easily be seen by the vehicle operator. The system controller switches between the two radar modes depending on which one is more appropriate to make use of one mode's strengths while avoiding the other mode's weaknesses. When there is no relative movement between objects and the vehicle, the frequency-modulated, continuous wave mode is used.

Abstract: A receiver for specimen slices, produced by slicing a tissue sample in a cryogenic microtome, includes an upper member pivotably attached to a lower member and forming a space therebetween for receipt of the specimen slices. Such receipt prevents curling and rolling of the slices, and facilitates easy transfer of the slices to an examination slide. The receiver is adapted to be pivotably and adjustably attached to the microtome, whereby it can be selectively pivoted away from the specimen slice receiving position, or otherwise adjusted for optimized tissue slice reception and storage.

Abstract: A pair of concentric cylindrical members are arranged for relative sliding movement with the lower end of the inner member being formed with outwardly projecting flexible blades. The blades are adapted to displace rubber guard elements covering a sink opening when the pair of members are received in a disposal unit, or in a sink opening without a disposal unit. The flexible blades are normally held against their outward projection when contained within the outer member, but upon sliding movement of the inner member axially relative to the outer member, will flex radially outward so as to maximumly displace the rubber guards. The resulting displacement establishes an improved unobstructed central passageway in communication with the disposal unit grinding hopper, whereby undesired foreign matter therein may be withdrawn with the use of elongated, slenderized tongs.

Abstract: An annular member received in a disposal unit displaces rubber guard members covering the sink opening while establishing an unobstructed central passageway in communication with the grinding hopper of the disposal unit. Lights supported on a lower portion of the annular member illuminate the interior of the disposal unit, which interior is accessed through the annular member central passageway by elongated and slenderized tongs for grasping and removing undesired foreign matter within the disposal unit.

Abstract: This invention relates to an instrument of a type known variously a a biopsy needle or cannula and used to gather tissue, and particularly soft tissue such as bone marrow, from living persons or animals for pathological study. The instrument retains a gathered tissue specimen by closing the end of a hollow member while the member is in the gathering position, and more particularly by deforming a flexible portion of the member. A pair of members are employed, one moving within the other. By a particular cooperation between the members, a flexible portion of the inner member is displaced or deformed to occlude an open, tissue receiving end thereof and thereby capture tissue and retain it against loss on removal of the instrument from the body of tissue into which it has been thrust.
