摘要:
A compensation circuit may include a current source configured to control an amplitude of a current pulse, a memory configured to store a plurality of duration values each corresponding to a set of one or more sensor electrodes of a plurality of sensor electrodes, and a pulse width controller configured to control a duration of the current pulse based on a first duration value of the plurality of duration values, and to apply the current pulse to a compensation node of a capacitance sensor during a measurement cycle for a first set of one or more sensor electrodes, where the first set of one or more sensor electrodes corresponds to the first duration value.

An active integrator for sensing capacitance of a touch sense array is disclosed. The active integrator is configured to receive from the touch sense array a response signal having a positive portion and a negative portion. The response signal is representative of a presence or an absence of a conductive object on the touch sense array. The active integrator is configured to continuously integrate the response signal.

A tool body (1) has a coupler for engagement with any of a variety of tool heads such as a spade head (3), and a hatchet head (4). A tool comprising the body (1) and a tool head (3-10) is a hammer action tool. It may be used as a fork, spade, chisel, hatchet, or any tool which would benefit from a hammer action. A tubular shank (21) and a hammer (22) are together a hammer weight which is pushed down by the user until it hits a receiver (23), driving the tool head. A spring (24) returns the hammer (22) and a shank (21) back up to the start position ready for the next hammer action. It also acts to push the tool head out against a work surface for overhead work such as chiseling. A spring (25), acting between a hammer impact part (22) and the handle (21, 27) takes the shock out of the impact for the user's hands. The shank (21) and the hammer (22) slide up and down together on the box-section receiver tube (32). A safety locking mechanism has a catch (30) biased to automatically lock the hammer unless the user presses a trigger in the handle.

The present invention relates to methods of using an aqueous composition or dispersion containing a water-soluble or water-dispersible synthetic polymer, and compositions formed thereof. The aqueous composition or dispersion is added to agricultural spray compositions, ink compositions, deicing or anti-icing compositions, latex paint and coating compositions, cleaner compositions, adhesives, fire-extinguishing chemical compositions, hydro-metallurgy/electro-winning compositions, compositions having organosilanes, personal care compositions, water-based hydraulic compositions, dust control compositions, and textile finish compositions, to impart properties including aerosol control, spatter control, shear stability, rheology control, transfer efficiency, oil/water reduction, sling control, emollient performance, film forming capability, surface activity, encapsulent ability, lubricity, thickening, and anti-wear capability, to the resultant composition formed thereof.
摘要:
A first integration capacitor stores charge from a positive signal portion. A second integration capacitor stores charge from negative signal portion. The voltage across the first and second integration capacitors is measured differentially. The presence of a conductive object proximate to a capacitance sensing element is detected based on the measured differential voltage between the first and second integration capacitors.

A vehicle tracking system central host comprises a memory cache processor for managing a plurality of memory caches and a storage device linked with the memory cache processor, for receiving messages from the memory caches and writing them to a database. There are n receiver ports each for receiving message packets of an associated protocol from remote vehicle on-board tracker units. There are also n receiver processors, each associated with a port and each receiver processor being for: reading message packets received at the associated port, performing initial processing of the message packets including adding headers to provide processed messages, and writing the processed messages to a log dedicated to the receiver processor. There re also n decoders, each associated with a receiver processor log and being for (a) instantiating a service object for each log, (b) executing each service object to instantiate a message object in which data from a current message is written as attributes of the message object such that instantiation of the message object normalizes the message and the normalized fields include a vehicle identifier field, and (c) executing each service object to repeat step (b) for each successive message in the associated log, and (d) executing the service object to write each message object to one of said memory caches. The ports, the receiver processors, and the decoders operate in parallel.

A golf bag (1) is provided that includes a main bag portion, and an accessory bag portion (3). The accessory bag portion may be either placed within a socket portion of the main bag portion such that the main portion and the accessory bag portion are integrated (4) to form a golf bag, or removed from the socket portion to provide access to an accessory bag that is smaller than the golf bag. The accessory bag portion includes a handle (15); and the golf bag includes a lock mechanism (24) that is operable to automatically lock the accessory bag portion in place relative to the main bag portion, when the accessory bag portion is inserted into the socket portion, and wherein once locked in the socket portion, the locking mechanism enables a user to lift the golf bag using the handle. The accessory bag includes an activation mechanism (16) operable, based on user initiation of an activation button, to actuate two or more support legs (11) from a first retracted position, to a second splayed out position operable to enable the accessory bag to achieve a self-supporting upright position. The activation mechanism includes a slider, a pivoting shoulder for each supporting leg, and a spring means connecting each pivoting shoulder to the slider, such that the user initiation of the activation button moves the supporting legs to the second splayed out position.
