A bar-coding system employs a unique bar code pattern which includes a code represented by a series of dark and light stripes that may be easily decoded by a very inexpensive reader with greater reliability. The bar-coding system generates binary data from the pattern which may be described in parts as follows: long light fields at each left and right end; a start bar at each end; right and left data fields; and a three-bit asymmetric pattern (light, dark, light) in the center that indicates the direction in which the pattern is moving past the read head. The coding sequence of the data fields is arranged from either end toward the middle of the pattern where the coding method reverses; therefore, a coupon or card passed through the reader in either direction will yield the same output. Only two widths of the light and dark stripes are used, and the stripes are read as pairs in succession. A reader includes a card slot which is shaped to an arcuate path which bends an inserted card made from a resilient material so that the card is pressed against the slot sidewall to enhance the reader's accuracy and reliability.

A battery-operated rotating sign employs a mechanically efficient speed-reducing mechanism and a power controller to reduce power consumption and, hence, increase battery life. The device is particularly suited to a ceiling-mounted, vertically-suspended rotating sign. A resilient power transmission strand extends from the vertical shaft of the motor to the sign which hangs from the bottom end of the strand. The power controller includes electrical circuitry having a timer which cycles between 'on' and 'off' periods. During the 'on' period, the rapidly turning motor shaft winds up the resilient strand; and during the 'off' period, the energy stored in the strand is released to the sign which turns slowly at the opposite end of the strand. Additional energy savings are provided by a photodetector circuit which disconnects the battery at night when operation of the sign is not desired. The apparatus further includes a device for mounting the motor to a suspended ceiling, including a mounting bracket which hangs from the ceiling tile cross bracing.

An electronic mosquito repellant sonically or ultra-sonically attracts male mosquitos. The presence of the male mosquitos repels the pregnant female mosquitos. The female mosquitos, as distinguished from the male mosquitos, are equipped with mandibles capable of piercing the skin of human beings. As a matter of fact, though, it is only the pregnant female mosquitos that require blood for incubation of the fertilized eggs that bite. Thus, the electronic device repels the biting female mosquito and precludes being bitten by mosquitos in an area covered by the output of the device.
