First Claim
Patent Images
1. In a keyboard having a plurality of keys that upon being pressed past a selection threshold generate a keystroke for entry into the current application, wherein the improvement comprises:
- means of sensing intermediate key pressure which is less than that required to generate a selection; and
programming in the application for generating feedback as to which key is subject to the intermediate pressure, wherein the user can change hand positioning to find the desired key before entering a keystroke.

26. A apparatus for registering the height of an individual and annunciating that height, comprising:
-
a compliant strip of material;
means for sensing position along said strip of material;
means for annunciating a height value;
computer processor operative coupled to said means for sensing ans said means of annunciating height and configured with programming for, registering the location along said strip wherein sufficient level of said contact pressure has occurred, converting the location data to a height value, converting the height value to a signal for said means of annunciating height, outputting said height value to said means for annunciating.

31. A system for controlling burner intensity on a stove, or similar, cooking element, comprising:
-
a transducer adapted for registering the cooking state of food elements being heated within receptacles by a specific heating element;
a signal processing element operably coupled to said transducer and adapted to discern the state of said food elements in response to the quantity being registered by said transducer;
a controller operably coupled to said signal processing element for receiving information on the state of said food elements;
an input device in communication with said controller into which a user can select the desired state that said food elements are to attain or be retained at;
a power control element operably coupled to said controller and adapted for modulating the power output of said specific heating element; and
wherein said controller generates at least one signal to said power control element that is responsive to the difference between the desired state as entered by said user and said state of said food elements as registered by said transducer;
whereby the power output of said burner is modulated so as to match the user input with the state of said food elements registered by said transducer. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40)

41. An apparatus for cleaning windows in multi-story buildings, comprising:
-
a drive mechanism adapted for traversing a set of tracks joined to a multistory building adjacent the windows of said building;
washer assembly attached to said drive mechanism and adapted for cleaning said windows;
means for sensing position along said tracks;
a controller operable connected to said means for sensing position, said washer assembly, and said drive mechanism, wherein said controller is adapted with programming for, determining the position of said drive mechanism along said track from input received from said means for sensing position along said track, activating said drive mechanism until said washer assembly is positioned in relation to a window, or a portion thereof, to be washed next, activating said washer assembly to wash all or a portion of a given window, determining which window or portion is to be washed next, repeating the above steps for all windows to be washed;
at least one power source configured to power the drive mechanism, washer assembly, means for sensing, and said controller. - View Dependent Claims (42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54)
