An engine system and a method of controlling a combustion process in an internal combustion engine are disclosed. The combustion process is based on compression ignition of a stratified air-fuel mixture using a high octane fuel such as gasoline. Multiple fuel injections may be used in a given combustion cycle. Fuel injection timing, EGR, exhaust rebreathing, late intake valve closing, and intake boost are controlled to enable autoignition over essentially the entire speed and load operating range of the engine, while providing reduced emissions, low noise, and low fuel consumption.

An apparatus and a method for inserting and displaying one or more signals during processing and display delays encountered in digital STB-receivers, including those delays encountered during channel changes. Moreover, a means for increasing the channel change delay period, while maintaining subscriber satisfaction, and thereby freeing up bandwidth for other services, is provided. These signals can be advertisements, entertainment, or other messages. When a channel change request occurs on a digital set-top receiver, a local watchdog module detects the channel change event and causes to be generated a signal that is immediately displayed on the TV, while the MPEG-2 subsystem of the receiver acquires, stores, decodes and presents the new program to the television. Providing advertisements or entertainment during the delay period allows for increase in the delay period thus allowing for higher compression and increased availability of bandwidth.

Novel system and methodology are provided for controlling a DC/DC forward converter having a transformer with primary and secondary windings, a reset switch, and a first switch coupled to the primary winding of the transformer. The control system involves a PWM control circuit responsive to an output signal of the converter for producing a PWM signal to control switching of the reset switch, and the first switch. A period of the PWM signal includes an on-time interval for enabling transfer of power via the transformer when the first switch is on, and a reset time interval for enabling reset of the transformer when the reset switch is on. A maximum value of the on-time interval is pre-set to provide sufficient time for the reset. The reset switch is turned off when the PWM signal goes from a first level to a second level. A first delay period is set between time when the reset switch turns off and time when the first switch turns on. A first delay control circuit is provided for reducing the first delay time when the on-time interval approaches the maximum value. Further, the converter may include a second switch coupled to the secondary winding of the transformer. A second delay period shorter than the first delay period may be set between time when the reset switch turns off and time when the second switch turns on. A second delay control circuit may be provided for reducing the second delay period when the on-time interval approaches the maximum value.

A child is encouraged not to sit close to the screen of television receiver. A base unit on the television receiver has a proximity detector that senses whether the child is within a preset range forward of the television receiver. In response to a range violation, the base unit transmits a triggering signal on an RF carrier to a slave unit. In response to the triggering signal, the slave unit transmits an OFF command on an infrared carrier to a standard infrared sensor built into the television receiver. The command is identical to the OFF command transmitted by a remote control associated with the television receiver. Since the base and slave units communicate via an omnidirectional RF carrier, the slave unit can be freely positioned to ensure adequate line of sight transmission communication with the television receiver via the infrared carrier.

Finally, analyze all the measured data to calculate the correct parameters for the control circuit of the flat panel display and set the parameters of the control circuit to the correct values.

A delay period timing system for a seeding implement with a feed control. A distribution network conveys products to the furrow openers, and a feeding mechanism controls flow of products into the distribution network. A flow sensor downstream from the feeding mechanism detects when products are flowing at a sensing location, and a timer measures a delay period between the time the feeding mechanism starts or stops flow and when the flow sensor starts or stops detecting flow. The delay period is adjusted to account for the location of the flow sensor. A method of determining the delay period includes determining the length of the distribution network and determining the speed of flow of the products. The system can be used on seeding implement with or without sectional control.
