A method of detecting presence or absence of a magnetic measurement probe at a measurement launch position in an electromagnetic coil of an ophthalmic instrument includes applying a temporary current pulse to the electromagnetic coil, detecting a counter-electromotive force voltage spike induced in the electromagnetic coil by the current pulse, evaluating a decay behavior of the counter-electromotive force voltage spike, and correlating the decay behavior of the counter-electromotive force voltage spike to presence or absence of the measurement probe at the measurement launch position.

Embodiments of the present invention relate to an electronic drive system for a battery powered ride-on toy vehicle.

Electronic drive system for a ride-on toy vehicle

An infant device, such as in infant swing, establishes a wireless connection with a parent's existing portable electronic device, such as a smartphone. The portable electronic device sends messages to control any of the functions associated with the infant device. The portable electronic device also sends video and voice to be output at the infant device, allowing the child to remotely see and hear the parent's face and voice. The infant device sends messages with status information on the system enabling the portable electronic device to remotely monitor the system. The infant device also sends messages to the parent's existing portable electronic device containing audio and/or video information recorded from the child, allowing the parent to remotely see and hear the child in the system.

An electronic learning device for receiving a book having a plurality of successive page spreads, at least one page spread having selectable content and an optically readable page identifier. The device includes a housing configured to receive the book, a position sensor in the housing configured to determine the location of the selectable content on the at least one page spread, an optical sensor in the housing configured to irradiate and detect the page identifier on the at least one page spread and control electronics in the housing operatively coupled to the optical sensor and to the position sensor and configured to synchronize sequential operation of the position sensor and the optical sensor.

Interactive electronic device with optical page identification system

A computer peripheral toy device is provided that connects to a personal computer and enables a child user to create drawings, animated figures, cards, posters, and other projects and items. The device includes a housing having a drawing tablet and a stylus that connects to the housing for use on the drawing tablet. There a plurality of buttons on the top surface of the housing that a user depresses when engaging in a drawing activity. Computer software is provided for installation on the personal computer in order to display data associated with a drawing activity. When executed by the computer, the computer software causes the computer to respond to the messages received from the controller to engage in a drawing activity using drawing style parameters based on which of the drawing style buttons, color palette buttons and design tool buttons are selected by a user.

Digital arts and crafts computer peripheral toy device

An electronic learning/teaching device operates with and without a printed sheet element having an arrangement of selectable content by means of a user responsive sensor array beneath a surface configured to receive the element. The sensor array is formed by cross-points of two sets of crossing conductive lines, one set being driven sequentially with a radio frequency square wave and the other set being sampled sequentially though a high impedance amplifier connection with an asynchronous detection circuit. Where more than one cross-point location is user activated, algorithms are used to identify one cross-point sensor location as the user activated selection.

A cable splicer chair is disclosed that is ergonomically sound in a wide variety of work environments. This seat includes a seat assembly having a backrest and adjustable legs that will allow the chair seat to be level regardless of the terrain upon which the chair is supported. The cable splicer chair includes convenient mechanisms for attaching tools that are used by the cable splicer and locating such tools optimally for an individual cable splicer.

Splicing chair

A color coordination cone which permits a hair colorist to examine color mixtures before actual application. It is comprised of an internally illuminated cone-shaped base apparatus over which one or more transparent color cones comprised of twenty-four longitudinal color bands in eleven shades is placed. The color cones are rotated one over the other to examine the effect of mixing one color with another. In another embodiment of the invention, a colorless, transparent conical sheath with external tracks in radial planes corresponding to the edges of color cone shade levels is slid over the color cone. Elongated strips in various hues are slid between certain sets of adjacent tracks so that a particular hue on a strip will be positioned over a particular hue on the color cone and the results determined.

Color coordination cone

A quickly demountable security-conscious door having a four-pin engagement with the adjacent door frame and having a plurality of rack and pinion mechanisms for movement of the hinge pin and lock bolt members into engagement positions with respective receptacles located in the door frame member. The door includes weather stripping provisions, operating knob rotational limits, and operating shaft spring assistance and uses Teflon.RTM. or other low-friction materials in appropriate frictional engagement positions.

Rapid dismount security door

A container opener which takes the form of an integral member which has a main straight body section. At one end of the main body section is attached the first extension which depends from the main body section at almost a right angle. The outermost end of the first extension is acutely arcuate so that it substantially bends over on itself with the outermost tip of the extension defining an angle of sixty degrees with respect to the plane of the main body section. A second extension is attached to the main body section and is to be generally curved and ending in a depending flange which is to be connectable with the locking tab type of pail lid.
