Abstract: An integrated circuit logic topology or architecture suitable for low voltage differential logic operating at radio frequencies is disclosed. The topology, referred to as enhanced pseudo common mode logic, is similar to and compatible with traditional CML, and provides the additional advantage of eliminating the need for level conversion between consecutive logic gates, thereby increasing the potential maximum operating frequency of subsystems implemented using the invention. The invention retains most of the advantages of traditional CML, and in addition permits the independent selection of output logic high level and output logic low level so that they may be matched with the succeeding circuit input levels.

Abstract: The invention provides a system and method of generating a number of inputs to the mixer elements in a direct conversion (homodyne) receiver configuration using Virtual Local Oscillator (VLO) techniques. These generated inputs meet the requirement that they must have a fixed and stable phase-relationship, as well as being correctly related in terms of their power spectra relative to the operating radio (RF), intermediate (IF), and baseband frequencies of the system, and that when applied to the mixer elements they permit the mixer elements to create internally the effect of applying the Local Oscillator signal at a suitable frequency.

Abstract: An “activity”-based system and method for on-line character recognition that requires reduced amounts of memory for code or data, is alphabet-independent, and can be trained by entering the alphabet once. The alphabet-independent nature of the algorithm, as well as the ease with which recognition may be optimized dynamically, makes it particularly well suited for writing in noisy environments (e.g., mobile or on a subway) or by persons with impaired motor skills or nervous conditions.

Additionally, a method is disclosed for separating the poultry parts into the spare rib-type products and the boneless meat patties.

Abstract: A series of staggered, overlapping coin carousels with coin stalls that receive coins, drive motors that operate to rotate the carousels and position the coin stalls so that the coins can be transferred between the carousels, and coin transfer mechanisms with gates that operate to move the coins between the carousels. An electronic controller is programmed to keep track of the positions and values of the coins in the coin stalls, and to determine and operate the appropriate drive motors and transfer gates for transferring coins between the carousels and for returning change.

Abstract: The present invention provides various embodiments of a gutter cap and a locking system that couples the gutter cap to the gutter. Because the gutter cap is not directly fastened to the gutter by the locking system, as is the case with many prior art designs, the cap is allowed to move slightly with respect to the gutter, and vice versa. This feature of the present invention reduces the likelihood that movement of the gutter will result in damage to the gutter cap, and vice versa. In accordance with the present invention, the coupling of the cap to the gutter is accomplished by using one or more clips that are configured to secure the cap to the gutter at one or more locations in a way that allows the gutter and the cap to move independently of one another.

Abstract: Wireless communications devices must handle a wide range of useful signal levels and must also cope with large interfering signals of nearby frequencies. They often use transconductance amplifiers/filters as building blocks as such amplifier/filters exhibit good characteristics of both amplification and filtering. The transconductance cells described make use of feedbacks which involve no signal conversions. As the result, the cells have high linearity and yet can operate at low voltage.

Abstract: A method and apparatus for converting a post-style poultry house to a clear span style poultry house. The apparatus includes a truss assembly including a center truss section adapted to be mounted to the roof beams and first and second outer truss sections adapted to be secured to the center truss section. The trusses are installed without the removal of the roof and without removal of the drinker and feeder equipment of the existing post-style poultry house. In installing the trusses, first the center sections of the trusses are attached to the roof beams and then the upper ends of the outer sections are attached to the center sections. Then the lower ends of the outer sections of the trusses are secured to the poultry house footers. Once the truss sections are all secured to each other and secured to the footers, the posts are cut away and removed.
