Abstract: A hanger for mounting an object on a surface such as a wall. The hanger includes a slot that receives a projection such as a nail extending from the wall. The slot is nonlinear and provides an entry path through which the projection travels to reach its mounting position. The hanger also includes slot branches extending from the slot, which together with the slot create a maze through which the projection travels when the object is attempted to be removed from the wall. The slot branches provide dead end paths that the projection may encounter when the object is attempted to be removed from the wall.

Abstract: A wind velocity measuring apparatus. The apparatus includes a thermal sensor and a processor operatively coupled to the thermal sensor. The processor is configured to receive a first temperature reading from the thermal sensor of a beginning temperature sensed by the thermal sensor and to receive a second temperature reading from the thermal sensor of an ending temperature sensed by the thermal sensor after a quantifiable amount of heat is applied to the thermal sensor for a quantifiable amount of time. The processor is further configured to determine a theoretical temperature based on the quantifiable amount of heat, the quantifiable amount of time, and the beginning temperature and to determine a wind velocity based on the difference between the theoretical temperature and the ending temperature.

Abstract: A temperature measurement apparatus allows for accurate temperature measurement in both the sun and the shade using two different thermal sensors. A black sensor has an infrared absorbent surface and a white sensor has an infrared reflecting surface. Using the measurements from these two sensors, a series of equations calculate the correct ambient temperature regardless of where the measurement device is located and ensures accurate readings using a performance check system.

Abstract: A primary device for a synchronous event system. In one construction, the primary device includes a solar panel operable to convert light into electricity; a receiver operable to receive a global positioning system time signal; a processor coupled to the receiver and operable to process the global positioning system time signal to produce a processed time component; a internal clock coupled to the processor and operable to store the processed time component and to increment relative to the processed time component thereafter to produce an internal time; and a transmitter coupled to the processor and operable to transmit the internal time to a secondary device for wireless reception by the secondary device and synchronization of the secondary device relative to the primary device.

Abstract: A time keeping system used to automatically adjust for daylight savings includes a processor having a preprogrammed internal clock module, a preprogrammed daylight savings time setting module, and a low power detection module. The preprogrammed internal clock module is programmed with a time, a date, and a year. The preprogrammed daylight savings time setting module is programmed with a plurality of daylight savings changes and automatically adjusts the internal clock to reflect a daylight savings time change. The low power detection module detects an operating power level. A primary battery is operatively coupled to the processor, and provides a primary power source to the processor. A frequency generating unit is also operatively coupled to the processor, and provides a frequency to the preprogrammed internal clock module. Furthermore, a clock movement unit is operatively coupled to the processor, and is configured to receive a series of timed-pulses from the processor.

Abstract: A radio-controlled clock movement for use in a radio-controlled clock which is synchronized with timing information supplied by a broadcast time signal includes a sound transducer for providing an audible signal representative of the strength of the received time signal. The clock is synchronized by setting the clock hands to an initial set position, decoding timing information from the broadcast time signal, calculating the relative distance to move the clock hands to make the displayed time synchronous with the decoded timing information and moving the clock hands the calculated relative distance. The initial set position is determined based on the desired time zone. In this manner, time zones are considered when setting the clock.
