 reduce significantly the length of the optical fibers in a transmission link between a monitoring location and a remote signaling source. While receiving a pedicure or a manicure at beauty salons, clients customarily have their hand and feet soaked in a basin of warm liquid. Soaking softens the skin and nails and has many other therapeutic benefits to include stimulating circulation of the blood and otherwise alleviating fatigue. Consequently, soaking is a particularly enjoyable part of having a manicure or pedicure.
In a salon setting, a soaking basin can be used by dozens of clients in a single day. So, hygienic practices regarding use of the basins are an important consideration. It is common and often required, that the basin is emptied and cleaned between uses. However, such repeated cleaning can reduce the life of the basin and can be time consuming. Instead, to cut down on repeated cleanings and yet to promote hygiene, many salons use makeshift liners such as plastic sacks, particularly those commonly used for groceries. Although generally effective, such plastic sacks lack sufficient rigidity to remain in place. Thus, leaking can be problem and, even if properly secured, wet sacks can feel odd against the client's skin. In addition, use of plastic bags lack esthetic appeal.
In current approaches, it is typically required that the technician lift the entire soaking basin filled with liquid to discard the liquid in between uses. Many such soaking basins include electrical components such as heating, vibration, and air circulation systems, adding to the weight of the soaking basin. Thus, such basins can be relatively heavy and awkward to lift.
It should, therefore, be appreciated that there exists a need for a soaking basin having a disposable liner that provides a therapeutic soak and is cost-effective to manufacture. The present invention fulfills this need and others. The invention relates to a circuit provided with an exposure measuring portion for sensor-controlled range finding where two linear semi-conductor image sensors are provided, each having individual sensor elements. Line segments corresponding to the two images and separately obtained from the object are projected onto the image sensors. Switching circuits are connected to the sensor elements which are switchable between two different states and an evaluator is provided for evaluating these two state sensor signals in dependence upon different position displacements with respect to a maximum correlation. A comparing sensor element is also provided and receives optically generated charge quantities corresponding to sensor elements in the image sensors.

 It should, consequently, be appreciated that there exists a motivation for a soaking basin having a disposable liner that provides a therapeutic soak and is cost - effective to fabricate. The present invention fulfills this need and others. The invention relates to a circuit provided with an exposure measuring portion for sensor - operate scope finding where two linear semi - conductor image sensors are provided, each having individual detector elements. Line segments corresponding to the two images and separately obtained from the object are projected onto the image detector. Switching circuits are connected to the sensor elements which are switchable between two different states and an evaluator is supply for evaluating these two state sensor signals in dependence upon different situation displacements with respect to a maximal correlation coefficient. A comparing detector component is also provided and receives optically beget charge quantities corresponding to sensor elements in the image sensors.
