A laser rangefinder bow sight adapted for use preferably with a conventional multi-pin bow sight having a frame and a plurality of sighting pins adjustably positioned on said frame. The laser rangefinder has a housing removably fastened to the bow sight frame. The housing supports a laser transmit section, a laser receive section, a precision timing section and a central processing unit (CPU) for measuring distance to a target coupled to an LCD display. The CPU also provides outputs to a plurality of range window indicator lights which are preferably LEDs. The indicator lights may be externally mounted to the bow sight pins or mounted within the rangefinder housing. In the latter case, a plurality of optical fibers are connected to the distance window lights in the housing. Each of the sighting pins is optically coupled to a separate one of the plurality of distance window lights via one of the optical fibers. The rangefinder is actuated via a remote trigger switch connected through the power supply in the housing to each of the sections. When the rangefinder is triggered, the CPU determines the target distance and activates one or more of the distance window LEDs for the range window or windows closest to the measured distance. Light is then transmitted via the optical fibers to the sighting pins, thus illuminating the one or two sighting pins corresponding to the measured distance. The display is held for a predetermined period of time or until the archer actuates the remote switch to take another distance measurement.

Laser bow sight apparatus

A modular laser-based surveying system is disclosed which comprises a laser-based distance measuring module and a separable compass module removably coupled to the laser based distance measuring module. Each of these modules may be operated as stand alone units as each has its own power supply and display. The system further may comprise a separate angle encoder module adapted to be coupled to either the laser distance measuring module or the compass module and a data logger or computer for processing data transmitted from any or all of the modules.

Modularized laser-based survey system

A light-weight, hand-held range finding apparatus of the present invention includes signal emitting circuitry and lens for emitting signals, and signal receiving circuitry and lens for receiving reflected signals, which are positioned within a chamber of a housing. The housing includes an upper section to which a sighting device is attached, a front end through which the emitted signals are emitted and the reflected signals are received, a back panel having a display device attached to said housing for displaying operational selections and range findings. An actuator is mounted adjacent the upper section and is operably connected to the signal emitting circuitry. The actuator is used to select desired operational selections displayed on the display device and actuating the signal emitting circuitry.

Compact laser-based distance measuring apparatus

An apparatus is disclosed for determining, in a first speed mode of operation, speed and range of a moving object and, in a second survey mode of operation, determining direct distances to an object and automatically calculate horizontal and vertical component distances to the object. Also disclosed is a system and method for data entry and retroactive reconstruction of the relative position of features and objects, in particular with respect to scenes such as transitory occurrences, utilizing a signal transmitting and receiving speed, distance and tilt angle determining apparatus or device. In a particular embodiment, the apparatus disclosed has especial applicability to tactical situation use by law enforcement personnel and the system and method in the on-scene recordation and subsequent ex post facto reconstruction of crime and traffic accident scenes by law enforcement officers. The system and method may be readily and efficiently implemented in conjunction with a laser-based speed, distance and tilt angle determining device otherwise usable for vehicle speed traffic monitoring functions utilizing either triangulation or baseline/offset mensuration techniques.

System and method for reconstruction of the position of objects

A portable data acquisition device, including a position-determining device and data collector, determines and stores positional data associated with objects positioned in a geographical area within sight of the device. Data representative of attributes associated with the objects are also stored in the device. The data stored in the device can be transferred to processing circuitry of a computer and absolute positional coordinates of the objects are determined. The absolute positional coordinates and the data representative of the attributes associated with the objects are placed in files accessible by geographic information system (GIS) software which utilizes the data to form a geographic information system (GIS) database from which GIS maps may be formed.
