Abstract: AN artificial fishing lure having hidden hooks recessed within the body thereof to prevent snagging on weeds, rocks or the like when the lure is moved through the water. A trigger is provided and is attached at one end to a fishing line, and at a second end to a spring hook assembly. The spring hook assembly is formed from a single wire member, and has a medially positioned bite portion engaging said trigger assembly, and opposed ends respectively terminating in hook arms and hook ends. Snapping the fishing line activates the trigger assembly, which in turn activates the spring hook assembly, causing the hook arms to extend outwardly from the body of the fishing lure through longitudinal slits therein.

Abstract: Apparatus for detecting the presence of an object moving relative to a vehicle within a location adjacent said vehicle, which location is hidden from the view of the operator of the vehicle; which comprises a first transducer mounted on the vehicle for transmitting sonic signals in a frequency range of about 30 to 40 Khz into the hidden location, a second transducer mounted on the vehicle in spaced relation to the first transducer for receiving a portion of the sonic signals reflected from an object present in the hidden location, a first high frequency (transmitter) audio amplifier powering the first transducer to cause the first transducer to transmit the sonic signals in the frequency range of 30 to 40 Khz, a second high frequency (receiver) audio amplifier for amplifying the signals received by the second transducer, a tuned amplifier for receiving a portion of the amplified signals from the receiver amplifier and being simultaneously coupled to the transmitter amplifier; the transmitting transducer, the
