Abstract: A waterproof thermometer for monitoring a food temperature during a cooking process includes a rechargeable battery for supplying power, a thermal sensor for measuring the food temperatures, and a processing unit for wirelessly transmitting data via an antenna. The waterproof thermometer further includes a first conductive part for containing the thermal sensor, the processing unit, and the rechargeable battery, a first insulating part for containing the antenna, a second insulating part, and a second conductive part. The first insulating part is surrounded by the second insulating part, and separated from the second insulating part by an air filled gap. The first conductive part, the first insulating part and the second conductive part form a first hermetic shell for providing waterproof function. The first conductive part, the second insulating part, and the second conductive part form a second hermetic shell for providing protection to the first insulating part from being damaged.

Abstract: A temperature monitoring system includes a thermometer and a first communication device. The thermometer counts a monitoring time, executes a measuring procedure to acquire a first temperature value and a second temperature value to determine whether to wirelessly broadcast a temperature information signal, and executes a time interval producing procedure after the measuring procedure to determine a time interval and to determine whether the measuring procedure is terminated. The first communication device receives the temperature information signal from the thermometer. The user may remotely monitor the temperature of a monitored object through the first communication device.

Abstract: An apparatus and a method for automatically establishing a new wireless link when the original wireless link between the apparatus and a commercially available FM radio receiver is interfered by other signal sources and reception conditions become poor, thereby eliminating the need to manually configure both the target FM radio receiver and the apparatus to a suitable FM frequency. The apparatus receives an audio signal, modulates and transmits the audio signal to the target FM radio receiver over a selected frequency, scans an FM spectrum for an alternative frequency, transmits an Radio Data System compatible command and a forcible switching signal to configure the target FM radio receiver to tune to the alternative frequency when signal quality of the received signal deteriorate sufficiently.

Abstract: An apparatus and a method for automatically establishing a new wireless link, when the original wireless link between the apparatus and a commercially available FM radio receiver is interfered by other signal sources, thereby eliminating the need to manually configure both the target FM radio receiver and the apparatus to a suitable FM frequency. The apparatus modulates an audio signal on a selected frequency and transmits the resulting FM signal to the target FM radio receiver, scans an FM spectrum for available frequencies, selects one of the available frequencies as an alternate frequency, transmits a Radio Data System compatible command incorporating the alternate frequency to configure the target FM radio receiver to tune to the alternate frequency when reception conditions are poor.

Abstract: The specification discloses a circuit that repairs flash memory faults by reconfiguring memory with symmetric and complementary fault areas and the method for the same. The method can reconfigure faulty flash memory devices so as to use the memory available. It employs a switching controller to determine the beginning and finishing time when data is read out from the flash memory and executes data line reconfiguration during the time the data is read out. The method then can use flash memory with symmetric and complementary fault areas.

Abstract: A nonvolatile memory unit includes a control circuit and a plurality of partially defective flash memory devices of the same kind. Each flash memory device is partly defective. The defective cells are in predefined regions. The defective areas of each device are complementary to non-defective areas of other devices. This ensures that each defective area of a device can be replaced by a non-defective area of another device, both mapping to the same region of memory. A switching mechanism facilitates writing to the flash memory devices simultaneously, examines read commands issued by the external circuit, and determines the associated data read cycle to read data from all of the attached flash memory devices simultaneously but selectively connects the data lines to ensure that data are read from non-defective areas. The unit can therefore be used as a non-defective despite its defects.

Abstract: An apparatus for tracing the locations of a line segment moving across a planar tablet is disclosed in the present invention, which includes a microprocessor, a positioning coil driving circuit, a plurality of positioning coils, a planar sampling circuit, a coordinate acquisition circuit and a counting circuit for the purpose of determining the location of a line segment relative to the planar tablet at a given time instant. A location of the line segment is determined by energizing a pair of positioning coils, each representing an end of the line segment, alternately and thereby achieving positional coordinates of these two ends. Repeating of such positioning operation results in a trace of the trajectory of movement of the line segment. A simple and effective position compensation method for offsetting the positioning error when locations of a physically installed or logically perceptible line object, instead of the line segment pointed by the two positioning coils, are to be traced.
