Abstract: Handpieces which comprise characteristic data storage systems electronically storing characteristic data, devices comprising these handpieces, methods of characterizing the device components, and methods of adjusting the device components based on stored characteristic data are described. The handpieces can be repeatedly connected to, disconnected from, and reconnected to an optical energy system comprising at least one optical energy source and at least one controller by a treatment provider. When the handpieces are connected to an optical energy source and a controller, the component characteristic data is accessed and used to adjust one or more of the components in order for the components to function together within a pre-determined tolerance. Once the components are connected and adjusted, the device can be used to provide an optical energy based medical and/or cosmetic treatment to a tissue such as, for example, human skin.

Abstract: An image viewed by a person is recorded in response to the pointing direction of the eyes of the person by using an optical sensor arrangement that simultaneously derives image segments corresponding with images seen by the person looking forward of his head and to both sides of his head. Alternatively, the sensor arrangement includes plural optical sensors for these images. One image of the plural sensors is selected for recording based on rotation of the head.

Abstract: An image capture system comprises a portable computer having a software-implemented subsystem and a connection to a sensor responsive still image digital camera including a control module and a FIFO buffer for storing more than one but less than two data image frames. When the image subsystem reaches a point during reading of a frame from the buffer where it is “safe” for the next image data frame captured by the image sensor to be stored in the buffer, the subsystem issues a “continue” signal, causing the next image data frame to be stored in the buffer. The “continue” signal is only issued if the buffer has sufficient capacity for the next frame to be completely stored. The “continue” signal minimizes frame loss, optimizes memory requirement, and sensibly drops frames when the host computer cannot handle image data at the same rate they are generated.

Abstract: A document platen for an electrostatographic reproduction apparatus which facilitates proper location of a document to be reproduced by such apparatus. In an electrostatographic reproduction apparatus having a planar member and a transparent member adapted to support a document to be reproduced by the apparatus, the planar member includes an opening defined in the planar member. Three corners of the opening have a rounded configuration and one corner defines a right angle. The transparent member is attached to the underside of the planar member so that the transparent member completely spans the opening. The right angle corner serves to direct an operator to properly place a document to be reproduced on the transparent member.
