Abstract: Novel reaction media for electron donating and electron accepting components in colour-change compositions are described. The compound is of formula (VI); R1, and R2 are independently selected from an optionally substituted linear or branched alkyl group, alkenyl group, alkoxy group, aryl group and an alkylene aryl group having from 5 to 22 carbon atoms; X1 and X2 are independently selected from —OC(O)—, —CO2— and O; Y1, and Y2 are independently selected from hydrogen, halogen, R1, —OR1; y is independently 0 or 1; and suitably the groups R1X1— and —X2R2 are independently in the ortho or meta position. The compounds are useful in ink compositions, writing implements containing the compound and medical and industrial applications in which temperature sensitive colour change may be required.

Abstract: A temperature-indicator product comprising a visual indicator comprising a thermochromic colour-memory composition and comprising an electron-donating colouring organic compound (A), an electron-accepting colouring organic compound (B) and reaction medium compound (C). The visual indicator comprises a first portion comprising a first thermochromic colour-change composition in its lower temperature state and a second portion comprising a second thermochromic colour-change composition in its higher temperature state.

The system further includes a remote device operative to receive battery voltage and temperature data from the battery monitor, generate a real-time indication of battery voltage, and generate predicted battery life data.

Abstract: A sensing apparatus for measuring at least one parameter includes at least one sensor for detecting at least one parameter and outputting a signal representative of the parameter. The sensing apparatus includes a memory for storing data and computer instructions and a communication component configured to transmit data representative of a value associated with the at least one parameter. A processor of the sensing apparatus communicates with the at least one sensor, the memory and the communication component. The processor receives output signals from said at least one sensor, and calculates at least one parameter based on computer instructions stored in the memory. The parameter is formatted in a human interface device (HID) compliant protocol, and provided to the communication component, which transmits the at least one HID compliant parameter value to a remote processing device.

Abstract: An automotive safety device includes a housing and a removable support assembly having a base and support members pivotally attached to the base and moveable between a first, closed position and a second, open position. Each support member is arranged directly adjacent to an outer surface of the housing in the first position. In the second position, the support members allow the device to be freestanding. A first light source is arranged on the housing such that the device may function as an emergency roadside light. The device further includes a tire pressure gauge, including a pressure sensor, a processor, and a display, wherein the processor is configured to output a value on the display indicative of a measured pressure.

Abstract: A hand-held device for measuring tire pressure and temperature including a pressure sensor, a temperature sensor, an optical pointer, a processor responsive to an output of the pressure sensor and the temperature sensor, and a display. The processor is configured to output a value on the display indicative of a measured tire pressure.

Abstract: A method and apparatus for testing batteries uses an audible voice prompt 35, 64 to enunciate the battery label or identifier that will be stored with the battery measurement in memory. Since the battery test technician must pay careful attention to the placement of the probes onto the battery terminal, the use of a voice prompt, rather than a visual prompt, allows the technician to keep his/her eyes on the test probes. If the label enunciated by the voice prompt does not match the label of the battery under test, the label on the tester can be reset to match the battery under test. In particular, a battery tester has a program which displays sequential numbers of battery labels that are stored with each battery's measurement data in memory. The sequence of labels corresponds to the sequential numbers marked on batteries in a string, array or matrix.
