Abstract: A bookmark that includes a light which can be carried by a book to light a page presented for viewing for reading. A portion of the bookmark is manipulable relative to another portion of the bookmark between a bookmark position and a light operating position with one of the portions receivable between a pair of pages of the book underlying the page presented for viewing that is lit by the light. One portion preferably includes a segment and the other portion preferably includes a segment with a joint that preferably includes a hinge disposed therebetween. A position actuated switch cooperates with at least one of the segments to turn on the light when the bookmark is manipulated into the light operating position. Such a bookmark can be configured to provide additional functions such as a magnifier, a picture frame, a clock and/or a calculator.

Abstract: A golf swing training device includes a pad having a light-reactive material on one side of the pad, and an indicator having a light source capable of striking the light-reactive material on the pad and creating a visual representation of the light on the pad. The pad includes printed indicia on the light-reactive material in order to illustrate the proper alignment and path for a putting stroke. An individual can place a golf ball on the pad and attach the indicator to the putter, and perform a putting stroke to strike the golf ball on the pad. The movement path of the putter head over the pad is visually illustrated by the reaction of the light source with the light-reactive material such that the individual can compare the actual putting stroke indicated by the light source path on the pad to the printed proper path indicia for the putting stroke.

Abstract: An optically or electronically transparent keyboard is disclosed having a key support, a display area, and keyboard transparency enabling keyboard operation from the front or rear. A keyboard, preferably of the QWERTY variety, is provided with transparent keyboard sections overlying one another. The keyboard sections when open dispose keyboard halves. QWERTY alignment is the same on the front and backside of the keyboard so that data entry is intuitive. Operation of the folding transparent keyboard can occur conventionally on a support surface or be enabled by support of the keyboard and miniaturized device in the palms of the user. In the palms of the user, the backside keyboard can be used with transparent viewing of the finger input. The sides of the keyboard are ergonomically shaped to position the hands properly, give better control of the keyboard while also making it easier to enter data.

Abstract: A voice actuated VCR controller includes increment and decrements buttons, and instruction button. Upon user battery insertion, and audio prompt requesting sequential setting of the day, hour, and minute occurs utilizing the increment and decrements buttons. Presuming the clock is set, and the device turned on, the decision tree protocol is activated. The protocol includes asking sequentially for the day, hour, and minute, AM and/or PM time for both the start and stop of VCR recording. Thereafter, the correct times are verified, the user instructed to turn on his VCR, insert a tape, and place the voice actuated VCR controller addressed to the VCR. In an alternate embodiment, the voice actuated VCR can make a presumption for VCR programming based on information in the controller, announce to the user the presumption and inquiring whether the presumption is correct, receiving an answer to the announced presumption, and in the event that the presumption is incorrect, receiving corrected information.

Abstract: A device for displaying power consumption rates includes a register for storing and displaying the cost of a unit of power, e.g., the cost per kilowatt hour as assessed by the local power company. A first display indicates the cost of power consumed over a first time period (such as an hour) based upon the then-existing instantaneous rate of power use. A second display indicates the cost of power projected to be consumed over a second time period such as a day, assuming that the then-existing instantaneous rate of power usage is maintained. A third display indicates the cost of power projected to be consumed over a third time period such as 30 days while fourth, fifth and sixth displays provide the instantaneous rate at which power is being consumed as well as totalized actual costs over two different time periods. A register is equipped with structure for adjustment whereby the cost stored in the register of a unit of power may be changed.

Abstract: A machine for treating a surface area within a boundary perimeter includes a self propelled chassis having a surface treating device mounted on it. A computing section is mounted on the chassis and a powered wheel (or each of plural powered wheels) has a motor module for receiving command signals from the computing section. A position sensor is coupled to the computing section for generating a feedback signal representing the actual position of the machine. A data loading device coacts with the computing section for transmitting data to such computing section. A data file stores graphic data developed from a graphic depiction representing the surface area to be treated as well as other data developed in other ways. The data file coacts with the computing section and transmits graphic and other data to it. The computing section is arranged for processing the data and the feedback signal and responsively generating command signals directed to each motor module.
