  • Patent number: 7209730
    Abstract: A telephone has a key pad with ten number keys arranged to dial the digits from 0 to 9 inclusive, each of these number keys being marked with a visual indicator denoting the digit which the number key is arranged to dial. The 1 and 9 number keys are provided with tactile indicators, distinguishable from one another by touch, so that a user can dial 911 by touch under conditions, such as in thick smoke or during a power failure, when the visual indicators on the keys are not readily distinguishable. The tactile indicators do not substantially obscure the visual indicators on the keys bearing the tactile indicators. An existing telephone may be retrofitted with the tactile indicators by providing two auxiliary members which can be secured to the 1 and 9 number keys, preferably with adhesive. Additional tactile indicators distinguishable by touch may be provided on other keys needed to dial 911 on cordless or cellular telephones, such as the on and send keys on such telephones.

  • Patent number: 5011412
    Abstract: An educational keyboard with removable keys, wherein musical tone generation for a given key is in response to correct placement of the key in its corresponding key slot, is disclosed. Incorrect placement results in a sour tone. Lights are also used to indicate correct and incorrect placement of keys. A computer interface for the keyboard allows a student to use pre-programmed interactive lessons tailored to the student's age and ability. Methods of teaching music theory and harmony with the keyboard utilize the student's left brain and right brain capabilities.

  • Patent number: 4807016
    Abstract: An etchant of PSG (14) or BPSG with high selectivity to substantially undoped oxide (12) includes a fluorine-liberating compound and a fluorine-scavenging compound. The fluorine-liberating compound is preferably a perfluorinated inorganic compound, and the fluorine-scavenging compound is preferably a hydrogen-liberating compound such as hydrogen. A particularly preferred inorganic fluorine-liberating compound is nitrogen trifluoride. In an exemplary embodiment, etch rate ratios of PSG to undoped oxide as high as 11 to 1 were obtained.

  • Patent number: 4468203
    Abstract: A teaching device, for use in a classroom, comprising a hand-held size calculator adapted to normally include a display for showing the numerical output of the calculator, and adapted to include a face plate having a plurality of keys which are arranged in a particular pattern and which bear indicia indicating the calculator function of the keys. The calculator does include a circuit for producing a signal in response to depression of the face plate keys of the hand-held size calculator. The teaching device further includes an enlarged keyboard including a plurality of enlarged keys arranged in a key pattern simulating the face plate keys of the hand-held size calculator, and indicia on the enlarged keys simulating the indicia on the faceplate keys of the hand-held size calculator. The indicia is readily readable anywhere within the classroom. The keyboard also includes a plurality of switches responsive to depression of the keyboard keys.

  • Patent number: 4378217
    Abstract: Terminal trainer keyboard and display apparatus for teaching keyboard operations and knowledge items and skills, including a keyboard array of touch keys representing individual characters and keyboard operations each having a switch associated therewith, a visual projector to be located within view of the trainee having a viewing screen onto which lesson information is displayed projected from a training film having sensor activating code bars beside the film frames denoting the correct key location for the displayed lesson instruction. The keyboard includes a light emitter at each key for illuminating its associated key, and an electronic circuit is coupled to the switches and receives correct key location signals from the sensors detecting the code bars to activate correct and incorrect readout counters to indicate the number of correct and incorrect key activations and to activate the light emitter at the correct key location when a key at an incorrect location is activated.
