摘要:
A hybrid vehicle and method of control are disclosed. An internal combustion engine and at least one traction motor are operated such that the combined output torque corresponds to one of a plurality of output torque functions, each output torque function having a distinct output torque at a maximum value of accelerator pedal position for an associated vehicle speed. The output torque function is selected based on a virtual gear number. The virtual gear number varies in response to driver activation of shift selectors or automatically in response to changes in vehicle speed.

The invention relates to a composition comprising (a) from 5 to 99 wt % of a modified polybutylene terephthalate random copolymer that (1) is derived from polyethylene terephthalate component selected from the group consisting of polyethylene terephthalate and polyethylene terephthalate copolymers and (2) has at least one residue derived from the polyethylene terephthalate component, and (b) at least 1 wt % of a filler component. In one embodiment, the invention relates to an article molded from the above-mentioned molding composition. In another embodiment, the invention relates to methods for making and methods for using the molding composition.
摘要:
A composition of matter comprising an article derived from a composition containing: a. from about 30 to 80 wt. % of a polycarbonate component, b. from about 5 to about 50 wt. % of a polyester component, wherein when polybutylene terephthalate is present in the composition, the polybutylene terephthalate is present in conjunction with at least one other polyester that is not polybutylene terephthalate; c. about 2 to about 25 wt. % of an impact modifier; and d. a gloss reducing effective amount of a multifunctional additive comprising at least one epoxy group. The invention also includes injection molding processes, thermoforming processes for making articles.
摘要:
Methods and systems are provided for raising the speed of a hybrid electric vehicle operating in an electric-only mode. During conditions when the vehicle is driven only by an electric motor, vehicle speed may be raised by spinning the engine unfueled using power from a system battery, while adjusting valve operation to reduce engine pumping losses. In this way, vehicle speed may be raised more efficiently and without damaging rotating transmission components.

Location information may be used to adjust the engine start/stop characteristics of a hybrid electric vehicle (HEV) in order to increase the amount of electric vehicle (EV) mode driving, particularly near a destination in which an ignition-off event may occur. Common ignition-off locations may be learned and stored in a database along with the number of ignition-off occurrences associated with each learned location. The vehicle may calculate current distance to a nearest ignition-off location stored in the database using positioning system coordinates and may determine whether to adjust one or more engine pull-ups based at least in part on the distance and the corresponding number of ignition-off occurrences.
摘要:
The method of the invention controls engine speed during engine starting for a hybrid electric vehicle that includes a battery, an engine and a generator, acting as a motor, whereby generator torque assists the engine to develop a stable running speed throughout an engine start event, particularly a cold engine start event, without violating battery power limits.

The present invention enables users to access shipping information pertaining to the shipment of parcels by utilizing an add-in module that is distributed from a remote server to the users. Specifically, the add-in module is invoked by merely selecting an action from a tool bar or menu associated with a text string in a document or spreadsheet either recognized by a MICROSOFT OFFICE® smart tag or highlighted by the user. The actions from which to select include but are not limited to tracking, time in transit, or shipping history. The add-in module is adapted to recognize the text string located in the document or spreadsheet and to transmit the text string to a database server connected to the network and adapted for receiving the text string, querying a database to retrieve shipping information corresponding to the text string, and transmitting the shipping information to the user via the communications network.
摘要:
The invention relates to a process for making modified polybutylene terephththalate random copolymers from a polyethylene terephthalate component. The invention relates to a three step process in which a diol component selected from the group consisting of ethylene glycol, propylene glycol, and combinations thereof reacts with a polyethylene terephthalate component under conditions sufficient to depolymerize the polyethylene terephthalate component into a first molten mixture; and where the first molten mixture is combined with 1,4-butanediol under conditions that create a second molten mixture that is subsequently placed under subatmospheric conditions that produce the modified polybutylene terephthalate random copolymers. The invention also relates to compositions made from the process.
摘要:
A safety valve for use in closed systems wherein there is a flow generator delivering oxygen or some other type of breathing gas to a patient. The safety valve of the present invention vents to the open atmosphere in the event that the breathing gas generated by the flow generator diminishes or terminates.
