Abstract:
An interactive display includes an optical sub-frame assembly and a sub-frame suspension that operates to isolate critical optical components of the interactive display from vibration and external forces applied to the interactive display. The optical sub-frame is affixed to the display surface and coupled to a frame of the interactive display via the sub-frame suspension to provide shock and vibration damping. The optical sub-frame assembly maintains optical alignment between optical devices such as a projector, one or more lenses, an illumination source, a display screen, and a light detector. The optical components of the interactive display are thus supported by the optical sub-frame, such that vibration and external forces applied to the interactive display are much less likely to affect the optical performance of the interactive display.

Abstract:
The display console includes a substrate having a viewing surface and a hidden surface. The display console further includes a display zone, a border zone, and a transceiver module configured to wirelessly send and receive data and coupled to the hidden surface of the substrate in the border zone. The display console further includes a hardware interface operatively coupled to the transceiver module, and configured to provide an image to the display zone.

US Classification:
395883
Abstract:
A circuit using a single transistor to detect the interface type to Which a combination pointing device is connected. The pointing device may be connected to a PS/2 interface, which generates a voltage greater than or equal to 0 volts, or a serial interface which generates a negative voltage. The transistor is activated when connected to the serial interface, and is inactive when connected to the PS/2 interface. The output of the transistor is sensed by a microcontroller within the pointing device. The microcontroller generates data for transmission to the PS/2 interface if the transistor is not active, and generates data for transmission to the serial interface if the transistor is active. An I/O pin in the microcontroller is used to sense the interface type and can also be used as an output in which the microcontroller generates control signals for use by the pointing device. This multitasking operation reduces the required pin count of the microcontroller, thus reducing cost.

Abstract:
A computer input device uses a standard mouse design and includes at least one thumb wheel or roller to provide three-dimensional cursor positioning. Left and right rollers, for use by left- and right-handed users, protrude from left and right sides of a standard mouse. The left and right rollers are axially mounted on left and right drive shafts that extend axially through left and right encoder wheels, respectively. Each encoder wheel forms part of a transducer for producing signals indicating movement or rotation of the wheel. These signals can be used for calculating cursor movement or for various other purposes in computer software applications. Alternatively, the rollers are coupled to switches or a single roller protrudes from the top of the mouse.
An input device capable of being connected to a computing device includes a housing having transducer electronics capable of manipulating an electrical signal to indicate movement of a portion of a user. At least one but fewer than four conductors are connected to the transducer electronics, and are each capable of carrying an electrical signal related to the input device. Each of the conductors is coupled to a connector that is capable of being coupled to the computer.

Abstract:
The capacitance of an unknown capacitor is measured with multimeter instrumentation employing a dual slope analog-to-digital converter. The initial voltage across the capacitor is measured and the capacitor is cyclically charged until the capacitor reaches a predetermined proportion of possible charge. The final voltage is measured. The voltage across the charging resistance is integrated over successive charging cycles to provide a value proportional to the charge delivered to the capacitor and this value is divided by the difference between the initial and final voltages.

US Classification:

Abstract:
A thermistor device includes plural thermistor elements in series, one or more of which is shunted with a varistor so that if such thermistor heats up and drops excessive voltage, the current therethrough is diverted to the varistor until other thermistors in series also heat to a high resistance state. The thermistor and varistor elements are thermally joined so that the various thermistor elements are rapidly brought up to temperature and prevent prolonged voltage drop across a protective varistor.

Abstract:
A protective circuit for the input of a multimeter is provided with series connected thermistors partially shunted by a varistor whereby overload voltage is distributed between the thermistors enabling protection at higher voltage levels. Shunt connected varistors protect primarily against transient overloads and are thermally coupled to the aforementioned thermistors to bring the thermistors more rapidly to their high resistance condition such that damage to the varistors is avoided and continued protection is provided.
