Title: Driver alerting system while the driver is using a mobile phone
Inventor: OKUDA SADAHARU
IPC: B60K28/06
Filed: 2000-01-06
Abstract: If a driver of a vehicle uses a portable phone 4, the system detects the use of the phone and then monitors the driving of the driver to sense for erratic driving and if so warns the driver of his driving. The use of a portable communication device can be detected by use of a camera 3 detecting the phone against a user head or by monitoring 5 radio frequency waves from the phone. If the use of a phone is detected speed acceleration and steering angle sensors 6a-c are used to check the running condition of the car. If there is a large change the vehicle speed or direction a controller generates a message to provide a voice warning 9 to the operator. A traffic system (10, Fig. 10) can be integrated into the alerting system by using a GPS receiver and information of the road ahead.

Title: I.c. engine control method
Inventor: KOTWICKI ALLAN JOSEPH
IPC: F02B31/06
Filed: 2000-10-16
Abstract: A method for controlling an engine, eg a direct-injection spark-ignited engine, having both an electronically controlled intake manifold inlet device, such as an electronic throttle 62, 94, and an electronically controlled intake manifold outlet device, such as a variable cam timing system, a variable valve timing system or a swirl control valve is disclosed. The method of the present invention achieves cylinder air charge control that is faster than possible by using an inlet device alone. In other words, the method of the present invention controls cylinder air charge faster than manifold dynamics by co-ordination of the inlet and outlet device. This improved control is used to improve various engine control functions. A desired engine torque, or change of torque, may be provided by changing the outlet control device or changing both the inlet and the outlet control device in order to generate a desired cylinder air charge amount based on a desired torque or desired change of torque.

Title: Service-providing system using purchaser terminal and data collating terminal
Inventor: HAMADA JIRO
IPC: G06F21/10
Filed: 2001-05-18
Abstract: A service-providing system is constructed by a network (1), a commerce-provider server (3) connected to the network (1), a purchaser terminal (2) connected to the network (1) and having an interface with a data holder (2a), a data reader (5), and a data-collating terminal (4) connected between the data reader and the network. The purchaser terminal receives services from the commerce-provider server and transmits a selected service and a purchaser identification number to the commerce-provider server, so that the commerce-provider server stores the selected service in correspondence with the purchaser identification number, and the selected service along with the purchaser identification number is written into the data holder. Then, the data reader reads the selected holder, and the data-collating terminal, having received the selected service along with the purchaser identification number in advance, collates the selected service and the purchaser identification number from the data reader with those of the commerce-provider server to verify whether a purchaser having the data holder is a valid purchaser.
Patent GB-2371805-A (GB)
Title: Separation of olefins from paraffins
Inventor: MUNSON CURTIS L
IPC: G01N30/02
Filed: 2001-05-24
Abstract: Methods for separating olefins from non-olefins, such as paraffins, including cycloparaffins, oxygenates and aromatics, are provided. The methods use metal salts to complex olefins, allowing the non-olefins to be separated by a variety of methods, including decantation distillation and gravimetric separation. The metal salts are dissolved or dispersed in ionic liquids, which tend to have virtually no vapor pressure, and which poorly solubilize the non-olefins. Accordingly, the non-olefins phase separate well, and can be distilled without carrying over any of the ionic liquid into the distillate. Preferred salts are Group IB salts, more preferably silver salts. A preferred silver salt is silver tetrafluoroborate. Preferred ionic liquids are those which form stable solutions or dispersions of the metal salts, and which do not dissolve the non-olefins. Further, if the olefins are subject to isomerization, the ionic liquid is preferably relatively non-acidic. The methods involve forming a solution or dispersion of a suitable olefin-complexing salt in an appropriate ionic liquid. An olefin-containing mixture is contacted with the ionic liquid/salt solution, and the olefins are adsorbed. After the paraffins are removed, the olefins can be isolated by desorption. The olefin-containing mixture can be in the gas phase, or in the liquid phase. The flow of olefin-containing mixtures over/through the ionic liquid can be, for example, co-current, counter-current, or staged in stirred tanks. Countercurrent is preferred as it is the most efficient. The methods can be optimized using combinatorial chemistry.

Title: Delayed deallocation of an arithmetic flags register
Inventor: RAMIREZ RICARDO
IPC: G06F9/318
Filed: 1999-12-30
Abstract: A microprocessor capable of delaying the deallocation of an arithmetic flags register is described. A system processes instructions of a first instruction set architecture which has an arithmetic flags register. The system also processes instructions or a second instruction set architecture which is not compatible with the first instruction set architecture. In order to process a first instruction of the first instruction set architecture that implicitly updates the arithmetic flags register, the arithmetic flags register shares a physical destination register with a general register containing a result for the first instruction. An instruction that does not update the arithmetic flags but would deallocate the register containing the arithmetic flags triggers the delayed deallocation mechanism of the present invention.
