摘要:
An insect trap method and apparatus is provided. The apparatus includes a durable housing formed from a single plastic sheet and configured to include a flappable hook and an enclosure having two open ends, such that the enclosure includes a plurality of surfaces. The apparatus also includes at least one insect trap liner, such that the at least one insect trap liner releasably attaches to at least one of the plurality of surfaces. The method includes inserting at least one replaceable insect trap liner into a durable housing. Within this embodiment, the housing is formed from transparent plastic and configured to include a flappable hook and an enclosure having two open ends, such that the enclosure includes an interior wall and an exterior wall. This method also includes the step of hanging the housing from the flappable hook onto a desired location.

A vehicle toy combination includes a wireless controlled toy vehicle having a mobile platform configured to move over a surface. A central controller on the platform is configured to control at least one aspect of the toy vehicle. A hand-held manually actuable wireless controller is configured to remotely control user selected movement of the toy vehicle. An optical receiver is attached to the platform to look downward on the surface and is coupled to the central controller. The receiver is configured to read a predetermined reflective pattern located on the surface over which the toy vehicle moves. Multiple vehicles can be controlled simultaneously with multiple wireless, manually operated controllers operating at the same frequency by initially synchronizing the controllers to transmit in non-overlapping windows.

Refracted ultrasonic waves are utilized to calculate tool standoff. An ultrasonic transmitter sends a wave toward (and into) the borehole wall at a critical incidence angle for refracted waves. The refracted wave travels along the borehole wall and continuously radiates energy back into the borehole at the critical angle. The refracted wave is detected by a receiver, and the travel time of the refracted acoustic wave from transmitter to receiver is measured and used to calculate standoff. By making repeated measurements at various azimuths (for instance, as the tool rotates), one or more caliper measurements can be made. The caliper measurements can be combined to yield two-dimensional geometry of the borehole. Measurements made at different azimuths and depths yield three-dimensional borehole geometry. Arrays of transmitter-receiver pairs can be used to obviate the need for varying azimuth.
