摘要:
A portable handheld device for wireless order entry and real time payment authorization may include a portable housing, a display carried by the housing, an order entry input device carried by the housing, a transaction card input device carried by the housing for reading user sensitive information from a transaction card, a wireless transceiver carried by the housing, and a processor carried by the housing and connected to the display, order entry input device, transaction card input device and wireless transceiver. The processor may be for wirelessly sending input order information, and encrypting and wirelessly sending the user sensitive information from the transaction card without storing and without displaying. The processor may also be for wirelessly receiving and displaying payment authorization information based upon real time authorization from a transaction card issuing entity.

A golf club counter-weighting system, viable for both original manufacture and after-marketing, features an expandable weight assembly that is easily installed at a designated location within a golf club shaft and expanded via a user tool so as to become reliably secured in place by frictional pressure against the surrounding shaft. In a primary embodiment, the weight assembly is made to be threadedly engagable by the opposite end of a dual-function user tool enabling the weight assembly, when unexpanded, to be conveniently moved axially for initial installation, relocation and/or removal.

The present disclosure relates to a lawn sweeper designed to collect debris, such as grass clippings and leaves, from a surface such as a lawn, and more particularly to a lawn sweeper with a tilt-able hopper frame and hopper bag that includes a handle such that an operator may tilt the hopper frame and hopper bag, using the handle, to empty the hopper bag contents. The hopper bag and hopper frame are connected to a lawn sweeper unit using a hopper rod which is inserted into two slots at the ends of two hopper support bars and secured within the slots by two corresponding latch plates, one latch plate at each end of the two hopper support bars. The latching mechanism allows the hopper frame and hopper bag to be easily removed from the lawn sweeper unit for storage.
摘要:
A master node is configured to receive, from a slave node, a request to perform a modified two-step synchronization (sync) operation in a manner that precludes transmitting a follow-up packet; generate a sync packet in a manner that includes information associated with a previous time that a prior sync packet was transmitted to the slave node; transmit the sync packet to the slave node; receive, from the slave node, a delay request packet; transmit, to the slave node, a delay response packet, where the delay response packet stores information associated with another time at which the delay request packet was received, and where transmitting the delay response packet enables the slave node to calibrate a clock, hosted by the slave node, to a master clock, hosted by the master node, based on the previous time and the other time.
摘要:
An exhaust aftertreatment system comprising a selective reduction catalyst, a NOx sensor or an NH3 sensor, a urea injector, and a dosing control unit, wherein the dosing control unit calculates the rate of urea injection by estimating the concentrations of NO and NO2 in the exhaust downstream of the SCR catalyst.
摘要:
A filter bag support structure, including a first section and a second section. The first section includes a pair of opposed alignment members located partially internal to the first section and extending outwardly away from the first section aligned to insert into the second section. The second section includes at least one annular member. The alignment members are receivable within the second section and have engagement members near a distal end. A locking member is removeably insertable between the opposed alignment members and inhibits the alignment members from flexing inwardly when the locking member is inserted and causes the alignment members to resist being removed from the at least one annular member when a tension load is applied that would tend to separate the first section from the second section to a greater degree than when the locking member is not present.
摘要:
A system and method is provided for confirming the identity of a user, where the confirmation is made using biometric data. The system includes an internal speaker having an audio port, which is positioned within the ear of the user, and is adapted for producing a signal having one or more frequencies. The system further includes an internal microphone having an audio port, which is positioned within the ear of the user, and is adapted for detecting a resulting signal including the signal produced by the internal speaker and any corresponding signal reflections. A determination is then made as to whether the resulting signal detected by the internal microphone matches the corresponding predetermined expected signal, based upon a prestored hearing profile.
摘要:
A cabinet assembly includes a base having a top surface and a bottom surface. The top surface is connected to a frame with a first face and a second face. The bottom surface of the base is adapted to allow rotation of the cabinet assembly. At least one shelf is disposed on the first face of the frame. A portion of a three-dimensional decorative tree is adjacent to the second face of the frame.
摘要:
A method and apparatus for delivering a device driver to an operating system without user intervention. One or more operating systems (e.g., different operating system programs, different versions of one operating system) execute on a computer platform. During booting of an operating system a device is identified for which a driver is needed. The driver is requested from a service processor of the platform, which includes memory or storage for storing multiple device drivers (or multiple versions of one driver, for different operating systems). The driver is retrieved from the service processor's storage and delivered to the operating system.
