Filed:

Jul 30, 2003

Appl. No.:

10/631450

Inventors:

Ahmad H. Atriss - Chandler AZ, US
Steven P. Allen - Mesa AZ, US

Assignee:

Freescale Semiconductor, Inc. - Austin TX

International Classification:

H03M001/34

US Classification:

341163, 341155

Abstract:

Methods and apparatus are provided for an analog converter. The apparatus comprises a first redundant signed digit (RSD) stage and a configurable block. The configurable block converts to a sample/hold circuit to sample a single ended analog signal. The sampled signal is then scaled, converted to a differential signal and provided to the first RSD stage. The first RSD stage outputs a bit value corresponding to the magnitude of the digital signal. In a next half clock cycle the first RSD stage calculates a residue that is provided to the configurable block. The configurable block is converted to a second redundant signed digit stage and generates a bit value corresponding to the magnitude of the residue provided by the first RSD stage. The first and second RSD stages cycle back and forth generating logic value each half clock cycle until the desired bit resolution is achieved. The configurable block is then converted back to a sample/hold circuit to start another conversion process.

International Classification:

H03M001/12

US Classification:

341172, 341155, 341161, 341162, 341163

Abstract:

An algorithmic or cyclic data converter uses an RSD stage having a switched capacitor network for efficiently scaling at least one externally supplied reference voltage. A reference voltage is scaled by using capacitor ratios that also function to provide an output voltage used as a residue output of the RSD A/D converter. The residue is used to generate a bit value corresponding to the magnitude of the residue. Two RSD stages cycle back and forth generating a logic value each half clock cycle until the desired bit resolution is achieved. In one form, the RSD stage scales the externally supplied reference voltage only by factors of less than one. In another form, the RSD stage scales the reference voltage by any scaling factor. A reference voltage scaling circuit separate from the RSD stage is avoided.

International Classification:

G08B023/00

US Classification:

340573400

Abstract:

A separation alert system includes a first component securable to a child, an elderly or disabled person, or an animal. A second component is securable to a person having responsibility for the child, the elderly or disabled person, or the animal. The second component includes an alarm which is activated whenever the second component is separated from the first component by more than a predetermined distance.

US Classification:

Abstract:

An electronic pool pump timer that controls the run time of the pump for a period of time each day depending on the date. In the preferred embodiment, the user enters the historical daily maximum and minimum pump run times for the specific pool and the system calculates the required time the pump will run on a given day. The customized run time is thus calculated as a function of the date and the minimum and maximum run times for a given pool. The system then self-adjusts the run time each day as necessary. The device comprises a data input means, a display, memory, and a controller. It may also include a manual override to allow the user to turn the pump on at any time. The device is connected to the pump motor. The device is connected to a power supply and may also include a battery back-up in the event of a power outage. To prevent the pool from freezing, the system may also include an air temperature sensor that triggers pump operation when the ambient air is below a given temperature.

US Classification:

131173, 131335

Abstract:

A smoke conditioning and filtration system is disclosed. The system mixes smoke created from a burnable substance, such as tobacco or other herbal substances, with liquid vapor. This causes expanding of the inherent hot gases and moisturizing and cooling of the smoke, thereby creating a more pleasurable smoking experience. The system also conditions the smoke produced from tobacco or other herbal substances by filtering out a portion of the particulates and congeals a portion of the oil contained within the smoke. Furthermore, the system blows smoke from a spout, eliminating the need to put one's mouth on the spout, thus creating a more sanitary smoking experience.

Abstract:

An analog-to-digital converter stage includes: a comparator and logic circuit having first upper and lower unscaled voltage trip points that are different than upper and lower residue voltage trip points; and a switched capacitor circuit. The comparator and logic circuit is configured prior to an initial residue calculation cycle to compare a magnitude of an unscaled input voltage to the first upper and lower unscaled voltage trip points, to generate an initial output bit, and to generate a voltage scaling and gain control signal. The switched capacitor circuit is configured to sample the unscaled input voltage, to receive a reference voltage, and to receive the voltage scaling and gain control signal for selectively controlling a subset of switches of the switched capacitor circuit to scale the unscaled input voltage sample and reference voltage and generate an initial residue voltage during a single operation of the initial residue calculation cycle.
