Abstract: A system, and method perform compliance checking of computer records for MLS services. The compliance checking includes detecting multiple-listing-service (MLS) contract compliance with a MLS, gathering MLS-related data regarding an MLS subscriber from at least one database, checking for a non-compliance incident of the MLS-related data with the MLS service requirements, and in response to detection of a non-compliance incident, trigger a computer-based resolution process to resolve the non-compliance incident.

Abstract: A system, and method perform compliance checking of computer records for MLS services. The compliance checking includes detecting multiple-listing-service (MLS) contract compliance with a MLS, gathering MLS-related data regarding an MLS subscriber from at least one database, training an AI engine with input data containing as features MLS service requirements that correspond to contractual obligations of the MLS subscriber under a MLS license, applying the MLS-related data to the AI engine, after the AI engine is trained, and checking for a non-compliance incident of the MLS-related data with the MLS service requirements, and in response to detection of a non-compliance incident, trigger a computer-based resolution process to resolve the non-compliance incident.

Abstract: Disclosed is a UHF-VHF combination channel selector for use with varactor diode tuners in which varactor control voltage is provided by a plurality of tapered potentiometers covering the various tuning segments. Non-detent, continuous channel selection is provided by rotation of a single control shaft to which is coupled a potentiometer wiper assembly. A substantially linear tuner control angular displacement versus channel number displacement over both frequency bands is achieved by compensating for varactor tuner nonlinearity over the VHF-band with complementary VHF selector potentiometers while hyper abrupt junction varactor diode manufacturing tolerances are compensated for by normalization of the UHF selector by means of upper and lower band tapered potentiometers.

Abstract: A limited-position television tuning system includes a read-only memory (ROM) dedicated to VHF channel coarse tuning information. UHF coarse tuning information and VHF/UHF fine tuning information are contained in an electrically alterable ROM (EAROM). Equalization information for equalizing both fine tuning information and automatic frequency control (AFC) information for VHF is contained in another ROM. The memories are addressed by a viewer-operated switch. Information is read out as pulse-width modulated (PWM) signals by counter-interrogated comparators. A hybrid scaling circuit includes a pair of operational amplifiers (Op Amps) and three transistors, with each PWM signal being applied to a separate transistor. The fine tune transistor, along with the receiver AFC signal, drives the first Op Amp which, in turn, supplies operating potential to the equalization transistor, the output of which is coupled to the input of the second Op Amp.
