摘要： An angle digitizer receives signal representing the sine and cosine of the angle to be digitized. The voltages are fed to orthogonal pairs of input terminals. Between each two input terminals is a set of equivalued resistors to form a resistor ring. At the junction of each pair of resistors is an output terminal. Each pair of output terminals is connected to the input terminals of a signal amplitude comparator which compares the magnitude of the signals at its inputs to give a digital signal in accordance with which is greater. For each comparator the output terminals of the resistor ring are selected such that the signals are in a direct antiphase relationship. An odd set of the comparators is activated first followed by the activation of the even set. Thereafter the binary output values of the comparators are interleaved to form a full digital word which is then tested to see if it is a valid digital word.

摘要： Apparatus for digitally indicating the bearing angle of a source of microwave energy includes an antenna array of a plurality of antenna elements equispaced about an arc of a circle in a plane. Connected to each of the antenna elements is a different input port of a microwave power dividing and phase transforming hybrid matrix. Some of the output ports of the matrix are connected to input ports of a plurality of digital phase discriminators whose outputs emit a coded combination of binary level signals. The outputs of the phase discriminators are connected to an ambiguity resolving means which transforms the binary level signals to an unambiguous digital word representing the bearing angle.

摘要： There is described a bar code reading device having an image sensor, a first operating state and an alternative operating state. In the first operating state the bar code reading device can be restricted from reading out image data corresponding to a maximum number of pixels of the image sensor. In the alternative operating state, the bar code reading device can be capable of reading out a maximum number of pixels of the image sensor. The bar code reading device can attempt to decode a bar code symbol represented in captured image data whether the first operating state or the alternative operating state is active.

摘要： Systems and methods provide for illuminating a subject using a light pipe that transmits light from a source. A method includes providing a light pipe, the light pipe defining an inner lumen through which the image sensor views the subject; providing a light source in alignment with a proximal portion of the light pipe; and using the light source, projecting a light into the light pipe and through the light pipe, the light pipe including a distal portion for providing a high-angle bright field illumination pattern on the subject with a first portion of the light and for reflecting a second portion of the light for providing a low-angle dark field illumination pattern on the subject.

摘要： An illumination system and method for use in a handheld symbology reader that employs a grid of reflecting elements applied to a transparent plate adapted to project a highly diffuse and uniform illumination on a subject. The grid defines a geometry with a large number of transparent spaces between grid elements through which an image of the subject can be acquired. A light source array is configured to project light into the grid at a right angle via a light pipe having a distal beveled edge or side projecting light sources. Another light source may be employed to illuminate second light pipe with a chamfered edge to create low-angle illumination.
