Title: Controlling fuel injector pulse width based on fuel temperature
Inventor: CLEVELAND TRENT J
IPC: F02D41/38
Filed: 1997-10-24
Abstract: A method and system for controlling the injection of fuel across a plurality of fuel injectors coupled together along a fuel rail in an internal combustion engine is provided. The method and system involve producing a reference fuel delivery control signal for each of the fuel injectors as a function of the desired fuel mass to be injected and subsequently adjusting the pulse width of each fuel delivery control signal as a function of the fuel temperature proximate each of the respective fuel injectors. The temperature of the fuel proximate each of the respective fuel injectors along the fuel rail is ascertained by measuring the temperature of the fuel near the inlet of the fuel rail using a temperature sensor and subsequently determining the temperature of the fuel proximate each of the fuel injectors based on the measured fuel temperature measured and the location of said fuel injector along said fuel rail.

Title: Semiconductor devices with p-n junctions
Inventor: CREES DAVID EDWARD
IPC: H01L29/861
Filed: 1998-04-30
Abstract: A power diode or IGBT is provided with regions 7,6 respectively of semiconductor material of high minority carrier lifetime and low minority carrier lifetime. For high frequency operation, low lifetime material is preferable, but this can result in undesirable transient current and voltage spikes. The regions of different lifetime material 7,6 are spaced apart in a direction parallel to the p-n junction 5 of the device, and in embodiments of the invention are arranged to intersect the junction. The maximum transverse dimension of the region 7 is less than twice the minority carrier diffusion length in that region. Several configurations are described which produce different voltage-current transfer characteristics in which the effect of unwanted transient signals is reduced. The difference in minority carrier lifetimes is produced by electron irradiation or implantation of Pt or Au.

Abstract: An angular contact ball bearing has an escape portion 3c formed by removing the comer between the inner surface 3f of the ring which contacts the shaft and the axially outward end face 3j, such that the escape portion 3c does not contact the shaft. The inner ring has a shoulder 3a, main body 3m and race groove 3g. Various relative dimensions are disclosed including the width rx of the escape portion 3c relative to the width L of the shoulder 3a, the area S of the shoulder 3a relative to the area S1 of a cut-out of the shoulder 3a, the relative height C1/C2 of two chamfers 3d, 3e of the main body 3m, the inclination angle of the axially inward end face 3h, the height ry of the escape portion 3c relative to the width of the ring i at the race groove 3g, and the thickness t of the main body 3m relative to the diameter d defined by the inner surface portion 3f. Other relative dimensions are disclosed. The above dimensions help to reduce the outwardly opening moment about a point P between the main body 3m and the escape portion 3c, reducing the floating-up of the inner ring and helping to reduce the creep or slipping between the ring and shaft.

Title: A tape system storage and retrieval process
Inventor: WATERS GERAINT
IPC: G06F17/30
Filed: 1998-09-28
Abstract: A tape storage and retrieval system is provided to facilitate the archival of machine data to tape and optionally to disk storage in a manner which enables the retrieval of the data in a batch or on-line processing environment. A hierarchy of storage levels is adopted for data objects within the system. The manner of the storage of the data object within the tape system is determined by the storage level which is changed over time to reflect the need for access to the data object. For example, those tapes storing data object allocated the highest level of storage may be stored in parallel on disks, may only be written so as to occupy only part of the tape volume, or stored on the tape system drive.

Patent GB-2333000-A (GB)
Title: Finite state machine coding of information
Inventor: SCHWARTZ EDWARD L
IPC: H04N7/26
Filed: 1998-11-06
Abstract: A finite state machine coder-based system comprises reversible wavelet transform (101), context model (102), FSM-coder (entropy coder) (103) and optional header processing (104) which convert between image data (105) and coded data (108). Input image data (105) is converted into a series of coefficients (each multiple bits in length) by the reversible wavelet transform (101). The context model (102) divides the coefficients from transform (101) into context bins. A probability estimate is generated within the finite state machine (FSM) coder (103). In one embodiment the encoding includes creating an interval based on the FSM state, which interval comprises a pair of subintervals having endpoints. One of the pair of subintervals is selected based on whether the input bit is in a most probable state. In one embodiment, one bit of the state indicates if "0" or "1" is more likely to occur for the next context bin and the other bits indicate how likely this state is to occur. This is divided into a number of probability classes and bits are coded by the FSM coder for each class. Bits are output corresponding to bits that match between endpoints of the one subinterval that occur from the most significant bit to, and not including, the first non-matching bit between the endpoints of the one subinterval. Sometimes no bits are output to code bits with probabilities greater than 50%.

Title: Alternate gas fuel burning system
Inventor: SPENCER BRYAN W
IPC: F23N1/00
Filed: 1998-12-18
Abstract: A fuel burning system comprises a burner (12) in communication with a burner supply pipe (14) having an automatic two-stage regulator valve (20) for controlling the pressure of fuel gas delivered to the burner. The burner supply pipe is normally fed by a primary supply pipe (3) delivering collected digester or landfill gas through an automatic three-way valve (26), but a secondary supply pipe (4) carrying natural gas may be selected by the three-way valve instead. The valves (20, 26) are electrically connected to a standard ignition module (30) by a pressure-sensitive switch (28) to detect the presence of digester or landfill gas in the primary supply pipe (3). When sufficient gas pressure exists in that pipe, the three-way valve (26) is operated to permit delivery of the digester or landfill gas to the burner supply pipe (14) and the regulator valve (20) is held in its high stage setting. If sufficient gas pressure is not present in the primary supply pipe (3), the three-way valve (26) connects the secondary supply pipe (4) with the burner supply pipe (14) and the regulator valve (20) is held in its low stage setting for burning natural gas.

Title: A safety device for vehicle window
Inventor: ENNERDAL LEIF
IPC: B60R21/08
Filed: 1999-07-06
Abstract: A safety device for use in a motor vehicle includes a restraining element which may be in the form of a net (4 in figure 3) initially stored within a housing (3) extending across the entire upper edge of a windscreen (2). Pull cords (5,6) attached to the edges of the net extend downwardly past guide means (7,8) located adjacent the lower edges of the windscreen to a centrally located drive mechanism (9). Further pull cords (10,11) extend from positions further towards the central part of the lower edge of the net, and initially extend around the outer periphery of the windscreen being retained by yieldable means. The pull cords (10,11) pass guide means (14,15) located adjacent the lower edge of the windscreen and thus to the drive mechanism. When a vehicle deceleration greater than a pre-determined rate is sensed the drive mechanism applies a tension to the pull cords (5,6,10,11) such that the net is drawn to a position in which it extends across the windscreen. Pull cords (10,11) may be wound in at a faster rate than pull cords (5,6) as after the drive mechanism is started they become slack due to being released from the yieldable material (see figure 3).
