Each device of a group of devices, in particular voice-controlled devices, is equipped with sound receivers and emitters and a short-range radio communication subsystem. Each device is caused to emit a test sound and, via its communications subsystem, a related timing-reference signal. Each device receiving a test sound and related timing-reference signal determines the transit time of the test sound. Using the measured transit times, the devices determine their distances one from another and, by exchanging these distances, the devices, or at least one of them, calculates the relative locations of all devices.

A position measuring system that includes a scale graduation, a scanning unit for scanning the scale graduation. An adjustment device that includes a displacement element for setting a position of the scanning unit with respect to the scale graduation and a gear-down mechanism arranged between the displacement element and the scanning unit, the gear-down mechanism converts a displacement movement of the displacement element into a shorter displacement movement of the scanning unit. The gear-down mechanism includes a lever arrangement with joints, which converts the displacement movement of the displacement element into a linear displacement movement of the scanning unit in relation to the scale graduation.

A method and apparatus for calculating, presenting, recalling and recording the maximum running speed of a user over a prescribed distance in miles per hour or meters per second. The result is shown in digital and iconic form on a liquid crystal display (LCD). The apparatus incorporates a micro-controller, a LCD, a motion sensor, press switches and, light emitting diodes. The motion sensor is used to generate a signal, in response to external motion, which is input to the micro-controller for use in a calculating the speed in accordance with a prescribed formula. Upon completion of running over a fixed time period or distance, a message is displayed on the LCD to indicated the maximum speed achieved by the user during an interval of the fixed time and over the prescribed distance. The apparatus may be adapted for use on shoes, a user's wrists, or the like, for the purpose of encouraging the user to run as fast as possible, and to ensure safety of the user at night.
摘要:
A hazardous area warning system with a non-directional magnetic field based proximity receiver for warning personnel of an attendant hazard. The receiver includes a x-axis receiver with an antenna directed in a x direction, a y-axis receiver with an antenna directed in a y direction and a z-axis receiver with an antenna directed in a z direction. The antennas may be a wire loop wrapped around a ferrite core. The output from each of the three receivers are combined in an adder. The combined result from the adder is representative of the distance between the receiver and a warning transmitter antenna. A comparator determines whether the received signal indicates an attendant hazard, i.e., the receiver is too close to the warning transmitter. The receiver wearer is warned of the attendant hazard, visually and/or tactilly, e.g., with warning lights and/or vibrations. An encoder encodes the signal indication and a transmitter transmits the encoded signal. A data link receiver (located, for example, at a potentially hazardous machine) receives the encoded signal from the proximity receiver. The data link receiver decodes the encoded signal and activates a safety indicator light in response to the decoded information, a green light indicating normal operation, a yellow light indicating a caution or potentially hazardous condition, and a red light indicating danger. The data link receiver may shutdown and/or disable the machinery in a caution or dangerous condition.

A distance measuring apparatus is provided which utilizes a light-section method capable of measuring both close objects and far away objects without adjusting the dynamic range of an imaging camera. The apparatus comprises: an image acquisition section for imaging reflected light which has been emitted from the apparatus, has passed through a slit, and has then been reflected off the surface of a target object; an emission control section for controlling the emission time of the slit light during the time an image is being scanned by the image acquisition section, and for changing the intensity of the received light in the image acquisition section; and a distance calculation section for calculating the distance to the object based on the image taken by the image acquisition section and a positional relationship between a light emission position of the slit light and an image position.
摘要:
A measurement device, i.e. a metrology tool, and a vehicle are combined to provide a mobile metrology in a fabrication facility. Peripheral equipment such as a device transfer unit, for, e.g., FOUPs in semiconductor manufacturing, an electronic control system with, e.g., a PC, monitor, and keyboard and optionally a vacuum pump is also provided in module frames of the vehicle. The measurement configuration particularly reduces bottleneck situations in equipment qualifying of processing tools during fast ramp-up phases of, e.g., semiconductor manufacturing facilities, thereby saving costs. The construction is based on PGVs or AGVs and allows a fast operation directly at the location of a processing tool. With the possible exception of power supply or operator control, the measurement configuration can operate fully autonomously.
