Patent BR-9912530-A (BR)
Inventor: BUTTERFIELD DANIEL KEYES
IPC: H04B1/40
Filed: 1999-07-27
Abstract: A hardware-efficient transceiver. The transceiver includes a digital circuit for converting baseband signals to intermediate frequency signals. A signal source provides a first periodic signal of a first frequency. A direct digital synthesizer provides a second periodic signal of a second frequency from the first periodic reference signal. An upconverter circuit digitally upconverts the baseband signals to digital intermediate frequency signals using the second periodic signal A digital-to-analog converter converts the digital intermediate frequency signals to analog intermediate frequency signals using the first periodic signal. In the transceiver implementation, the digital circuit upconverts a first transmit signal from a first frequency to a second frequency in response to the second periodic signal and provides a digital transmit signal in response thereto. A second circuit is provided for converting the digital transmit signal to an analog transmit signal. Transmit and receive circuitry are provided for transmitting the analog transmit signal and receiving an analog receive signal, respectively. In a specific embodiment, the analog receive signal is digitally downconverted to provide a digital receive signal in response to a second periodic signal. A significant feature of the invention resides in the provision of the first and second periodic signals with a single local oscillator. A direct digital synthesizer is included for generating one of the reference signals from the output of the local oscillator. The transmit circuit includes a delta-sigma digital-to-analog converter having the first periodic signal as an input The delta-sigma digital-to-analog converter has a low-bit digital-to-analog converter and a delta-sigma modulator. In the illustrative embodiment, the low-bit digital-to-analog converter is a 1-bit digital-to-analog converter and the delta-sigma modulator is a sixth order delta-sigma modulator. The delta-sigma modulator includes amplifiers with approximately the following gains: 3/2, -3/4, 1/8.

Title: Injector dosing pump - provides accurate dosing without positive - displacement pump
Inventor: WALTER ARNOLD
IPC: C02F1/68
Filed: 1969-10-14
Abstract: A dosing process supplies dosed substance and liquid vehicle into the main body of liquid by using an ejector pump and operates on the following cycle; the pump draws a known quantity of dosing substance from a metering vessel, leaving the vessel under vacuum. Vacuum is maintained by a valve (e.g. a non-return valve) between the metering vessel and pump suction. Then a second valve is opened on the inlet side to the metering vessel, so that the vessel is refilled, by suction from a reservoir of dosing substance. The cycle can then be repeated, e.g. at intervals determined by the rate of the main liquid flow.

Title: Varying duration of a bi-level signal pulse in order to control the shape of the pulse envelope of an amplifier output signal
Inventor: GOODWIND STEPHEN
IPC: H03F1/02
Filed: 2000-06-20
Abstract: A control signal 66 for an amplifier 42 can be switched between a high and a low level to control the shape of the pulse envelope 64 of the amplifier output signal. The duration over which the control signal attains its high level is varied to control the shape of the envelope. This envelope control is necessary to allow signals of various power levels to fit into the envelope. Preferably a multilevel signal (e.g. form a DAC) is combined with said control signal in order to more finely control the envelope shape. The invention removes the need for a high-resolution DAC for envelope shaping. Such apparatus is suitable for use in a TDMA system.

Abstract: A dry air filter 4 for a vehicle internal combustion engine comprises a housing 5 containing a filter cartridge (7, Fig 2) and a preliminary dust separator (6, Fig 2) with an outlet 8 supplied with compressed air to clean the outlet 8 of dust. Preferably, the compressed air and dust from the preliminary separator exit the outlet via an attached discharge valve 10 which may be biased into a closed position and opened by the compressed air. An air line may pass through the outlet wall 8 to deliver the compressed air supply from an on-board compressed air generating system and may be provided with a nozzle 12 to improve the ejector effect of the air flow. To enhance the cleaning action the nozzle may be mounted with a funnel shaped hood (13, Fig 2) or may comprise a venturi (15, Fig 3). Compressed air may be delivered to the outlet and valve continuously or intermittently to prevent a build-up of dust blockage and this eliminates the need for separate, regular checks to ensure correct operation and cleaning of the valve. The filter may be used in utility vehicles fitted with internal combustion engines.
