Abstract: A hand held personal alarm incorporating a high intensity light and loud horn and further incorporating a plurality of switches that are located a distance apart that prevents their actuation by the digits of a single hand or by pressing the alarm against a single surface. The switches provide the only means of deactivating the alarm once activated. An alternative embodiment includes a timing circuit that prevents deactivation of the alarm for a set period after activation. Both schemes prevent easy deactivation of the alarm by an assailant, thereby providing more protection than with conventional hand held alarms.

Abstract: A method and apparatus for advance warning signaling to a motorist of an ice condition on a driving surface. The method steps include mounting a plurality of traffic signalling devices along a driving surface for sensing the prevailing temperatures and thereby continuously signal a motor vehicle operator of the changes in temperature as he approaches a driving surface subject to freezing to permit him to take any necessary precautionary corrective action in driving the motor vehicle. The signalling devices utilize thermostat elements for sensing a narrow temperature range adjacent the freezing temperature and provide visible signals, preferably two colors for signalling a warm or nonhazardous temperature, a cold temperature signalling a frozen driving surface or a combination or mixture of the colored signals to permit the motor vehicle operator to be warned, in advance, as he approaches a driving surface that is becoming colder, leading to a stretch of a driving surface that may be frozen.

Abstract: The present invention relates to vehicle breath monitors, and in particular to a vehicle breath monitoring system which either inhibits the starter motor solenoid of a motor vehicle or gives other indication when a driver's breath sample has an alcohol level above the legal limit. The system comprises an electro-chemical fuel cell assembly, which measures the level of ethanol of a breath sample supplied by the driver. The output of the fuel cell is fed to a microprocessor which uses the data as well as data of the ambient condition to determine the alcohol level of the driver's blood. The operation of the system requires the driver to use the system prior to the initial start of the motor vehicle, and a second repeat test to ensure that the alcohol level has not risen over time. If the tests are not passed the system gives an indication to the driver of the results so that the driver can act accordingly.

Abstract: A method of monitoring from a remote location each of a plurality of golf carts as they travel through a golf course. The Pro Shop, or other convenient location, and each golf cart are equipped with both transmitting and receiving apparatus such that wireless, two-way signals for a variety of communications may be sent between the carts and Pro Shop. Additional receiving and transmission apparatus is provided at a fixed location remote from the carts and Pro Shop such that the Pro Shop may receive signals which will establish the bearings of each cart on the course. Through circuitry and computer programming which performs triangulation procedures on the signals, the locations of each cart on the course are displayed upon a monitor board. From the location information thus received, warning signals may be sent to the carts of slow playing groups which are causing bottlenecks at particular holes.

Abstract: A door mat alarm is set forth including a flexible mat and encapsulated pressure switches positioned in a matrix throughout the mat whereupon compression of the flexible mat relays pressure to the switches and activates a remotely positioned transmitter to actuate an alarm. A modification of the instant invention includes a transmitter encapsulated adjacent a forward edge of the mat to relay a signal to a remote receiver portably carried by an individual.

Abstract: A security installation includes a primary barrier section protruding upwardly from a substrate and extending along the substrate in a first direction, a secondary barrier section protruding from, and extending along, the primary section, with the secondary barrier section being movable with respect to the primary barrier section in a second direction extending transversely to the first direction, and sensing means for sensing movement in the second direction of at least a portion of the secondary barrier section relative to the primary barrier section.

Abstract: A warning apparatus alerts a home owner to unsafe temperatures in the stove pipe of a wood- or coal-burning stove by signaling an alarm if the pipe gets too hot, thereby providing a warning against a potential fire hazard that can be caused by creosote build-up.
