1. An apparatus for detecting an object, comprising:
- a) a support;
b) emitter means supported by the support, and operative for transmitting radiation away from the support into an emission space;
c) sensor means supported by the support and having a sensing space, said sensor means being operative for receiving radiation directed by an object located in the sensing space to the sensor means, and for generating an electrical signal indicative of the presence of the object in the sensing space;
d) at least one of said sensor means and said emitter means including means for shaping at least one of said spaces to have a generally thin, screen-like volume having a cross-sectional width and a cross-sectional thickness less than said width substantially throughout said volume; and
e) said at least one of said spaces lying substantially entirely within the other of said spaces.

14. An apparatus for detecting an object, comprising:
-
a support having a plurality of sections arranged in a substantially closed configuration; each section having an emitter means for transmitting radiation through a single exit port away from a respective section into an emission space, and a sensor means having a sensing space, and being operative for receiving radiation directed by an object located in the sensing space to the sensor means of the respective section; each sensor means being operative for generating an electrical signal indicative of the presence of the object in a respective sensing space; and at least one of said emitter means and said sensor means of a respective section including means for shaping at least one of said respective spaces to have a generally thin, screen-like volume having a cross-sectional width and a cross-sectional thickness less than said width substantially throughout said volume, all of the screen-like volumes extending along the substantially closed configuration. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
