2004 results about "Electronic instrument" patented technology

There is disclosed a portable electronic instrument (1) including a case (2) and a user interface (11 to 15) for selecting the functions of said portable electronic instrument, this user interface including at least a first control member (11) mounted to be mobile in an assembly orifice (3a) arranged in the case so as to have a translation travel along an axis of actuation (X—X), said control member being able to be actuated by pressure to be brought from a position called the non pushed-in position to a position called the pushed-in position and to generate in response a control signal (SEL). The control member includes an electrically conductive stem (100) which passes through the assembly orifice and which includes first and second ends opening out respectively inside and outside the case, said stem being adapted to allow transmission of electric signals from and / or to the portable electronic instrument, when the control member is brought into said pushed-in position. This electronic instrument further includes means (3, 30, 40; 35, 40) for bringing the stem of the control member to a determined electric potential when the control member occupies the non pushed-in position and for interrupting the connection of the stem of the control member to the determined electric potential when the control member occupies said pushed-in position and for thus allowing transmission of said electric signals from and / or to the portable electronic instrument.

An instrument caddy and protection device is disclosed having a retentive pocket configured to closely adapted to, retain against displacement and protect an electronic instrument therein such as, for example, a multi-meter. The instrument caddy includes at least one magnet that enables the caddy to hold an instrument against a metallic surface during use while simultaneously protecting the instrument against breakage. Alternate embodiments of the caddy are disclosed wherein the retentive pocket is initially filled with sectioned and removable foam insert material enabling custom sizing of the retentive pocket so as to adapt to an instrument having given dimensions. In addition, preferred embodiments of the caddy provide for passageways for test cables and / or instrument straps to be attached to the instrument while it is held with the retentive pocket. Further embodiments are disclosed which include a magnetic shield incorporated within the caddy and positioned between the retentive pocket and the at least one magnet so as to protect the instrument against magnetic interference from either the caddy magnet(s) or interference originating from the surface upon which the caddy is placed.

A power transmission control device provided in a power transmission device of a non-contact power transmission system includes a drive clock signal generation circuit that generates a drive clock signal specifying a drive frequency of a primary coil, a driver control circuit that generates a driver control signal based on the drive clock signal, and outputs the driver control signal to a transmission driver, a waveform detection circuit that detects a change in waveform of an induced voltage signal of the primary coil, and a control circuit that performs foreign object detection based on a detection result of the waveform detection circuit. The drive clock signal generation circuit outputs the drive clock signal set at a foreign object detection frequency during foreign object detection, the foreign object detection frequency being a frequency differing from a normal power transmission frequency.
