Abstract: A touchscreen device is configured to display a number of user interface elements in accordance with a menu hierarchy. Upon receipt of a predetermined touchscreen gesture (e.g., the circular motion of a manipulator) the menu hierarchy is bypassed and the user is given immediate control over a selected function, for example, a tuning function such as audio volume, screen contrast, and the like.

Abstract: Applicant's invention is of an improved flywheel exerciser and of an improved handle for engaging the exerciser's cord. The cord segments on either side of the flywheel are securely engaged by pinch grip blades within the two handles' body. Because the cord is easily disengaged from the pinch grip structure, the spatial separation of the handles is easily adjusted for different users. A two-part grommet structure eases the assembly and cord replacement for the exerciser. Applicant's handle, particularly a modified version which can be used to grasp medial sections of a cord, can be used to engage cording in many contexts other than that of use for a flywheel exerciser.

Abstract: A grade calculating circuit (FIG. 1) used for fuzzy inference computation is disclosed. The circuit calculates input label grades based on the relationships between input data (Xi) and the input labels, defined by membership functions (MF) having at least one inclined line segment (FIG. 3), said grades having the upper and lower limit values (g.sub.max, g.sub.min). The circuit comprises: memory (20) for memorizing the input label membership functions by storing, for each of the membership functions, a function form type code, a bending point (Xo) at an end of the inclined line segment and a multiplication rule which designates a multiplier (2.sup.n +2.sup.

Abstract: A microcontroller is provided having an on-chip electrically erasable programmable read-only-memory (EEPROM), which is user programmable via a programming register. The microcontroller includes a low voltage program inhibit (LVPI) circuit which is combined with the existing EEPROM design. By integrating the LVPI circuit into the EEPROM, the EEPROM may be protected without disabling the entire data processing system. If the supply voltage (V.sub.DD) falls below a predetermined voltage level, the LVPI circuit inhibits the use of the EEPROM programming register, thereby preventing the CPU from programming or erasing the EEPROM. A comparator in the LVPI circuit compares a precision reference voltage to a voltage divided off of the power supply (V.sub.DD), and provides a output signal to the EEPROM programming register. During normal operation, the comparator output signal is a logic low, which enables the user to program or erase the EEPROM, via the programming register.

Abstract: A method and apparatus for post-packaging testing of one-time programmable memories provided means for assuring that each cell of the memory will appear to a customer to be erased and that it is capable of being programmed. The preferred embodiment of the invention is a microcomputer including one-time programmable memory, but the invention also includes memory-only devices. Marginal reading method and apparatus provide for detecting the threshold voltage of memory cells below the level at which the cell appears to the customer to be erased and marginal programming method and apparatus provide for slightly increasing the threshold voltage of cells in order to ensure their programmability.

Abstract: A write protect mechanism for a programmable read-only memory prevents writes to the PROM unless a protect register contains predetermined information. The protect register is itself a write protected control register. The predetermined information cannot be written into the protect register except during a short, predetermined period after the occurrence of an event such as a reset. The protect register may be written to with information other than the predetermined information at any time. The preferred embodiment comprises a single-chip microcomputer with on-board electrically-erasable programmable read-only memory which is write protected in several, separate blocks.

Abstract: A single-chip microcomputer comprises at least two separate and independent electrically erasable programmable read only memories (EEPROMs) on-board which may be independently programmed, erased and read. Each part of the split EEPROM has its own data bus and address bus. Programming and erasing is controlled by a program register which has separate bits for configuring and latching the data and address buses of a selected EEPROM array, for providing programming voltage to the array of choice and for choosing between programming and erasing the selected array. The split EEPROM provides versatility to the user in allowing one part of the EEPROM to be programmed while the program stored in another part of the EEPROM or RAM may be read and utilized. In addition, test time and effort of the microcomputer may be considerably reduced.
