A sheet placement device includes a placement member on which a sheet is placed; a limiter that is movable with respect to the placement member to limit a position of an end of the sheet placed on the placement member; a contact member provided in the limiter and to be displaced by contacting with the end of the sheet; and a detector that detects displacement of the contact member. The detector is provided in the placement member.

A winding machine for web-type materials, in particular film materials, comprises a feeding device and at least one winding shaft which is capable of being driven and designed to receive a winding core for the winding of the web-type film material, wherein the winding machine is allocated a system for regulating and/or reducing an electrostatic charge of the web-type material during the winding process.

A kit for dispensing disposable stethoscope covers and other instrument covers is provided. The kit may include a cartridge and a dispenser for automatic touch-free dispensing of disposable stethoscope covers. The kit further includes a first spool having a roll of backing member with disposable stethoscope covers disposed thereon and a second spool for receiving the spent backing member after a disposable stethoscope cover has been removed, self-contained within the cartridge. The cartridge is inserted within the dispenser so that a user may insert a stethoscope head through a window of the dispenser to attach to a disposable stethoscope cover. Alternatively, the cartridge or cassette may be comprised of disposable instrument covers so that a user may insert the instrument near or through the window of the dispenser for application of the instrument cover directly to the instrument. The kit may further include a proximity sensor for detecting a user.

A device (100) includes a sensor (101) to determine a capacitance between a first metal piece (209, 309, 409, 509, 609, 709, 809, 909) coupled to a paper tray (213, 413, 513, 913) of a printing device (206, 306) and a second metal piece (207, 307, 407, 507, 607, 707, 807, 907) coupled to a paper width adjuster (212) of the printing device (206, 306).The device (100) also includes a controlled (102) coupled to the sensor (101) comprising a processor (103) in communication with a memory resource (104) including executable instructions to determine a size of paper in the paper tray (213, 413, 513, 913) based on the determined capacitance.

Various embodiments of the present technology may comprise methods and apparatus for increased sensitivity of a capacitive proximity sensor. The method and apparatus may comprise a sense electrode and a drive electrode configured to create at least one inflection point corresponding to an increase or decrease in rate of change of capacitance within one or more sensing regions of the electrical field of the capacitive sensor. In alternative embodiments, the sense electrode may be configured to create multiple zones that may be used to indicate a desired signal such an upcoming replacement period and a replace now period.
