An architecture for an integrated circuit with in-circuit programming allows real-time modification of the in-circuit programming code and other code stored on the chip. The architecture utilizes a microprocessor and control logic on an integrated circuit having a single non-volatile memory that stores instructions and data, such as in-circuit programming and user code, and input/output ports and related structure for exchanging data with an external device. Using in-circuit programming code stored on the chip, the chip interactively establishes an in-circuit programming exchange with an external device to update data and instructions including the in-circuit programming code. Input/output conflicts during in-circuit programming can be avoided by employing a memory controller to handle at least part of the in-circuit programming operations. The memory controller allows the in-circuit programming code to be updated in real time.

A golf practice and exercise device has an elevated arm from which an impact object is suspended for swinging movement. The object is positioned with a clubhead impact target in position for striking by the clubhead of a golf club swung by a golfer. The resistance to the impact of the golf club is adjustable. A sensor detects the magnitude and velocity of the striking force, and a display displays an indication as to how far a golf ball would have gone after being struck with a force and velocity of the detected magnitude.

The invention belongs to the technical field of automobile detection, particularly relates to impact resistance detection equipment for automobile shock absorber support production, and provides the following scheme for solving the problems that impact detection equipment of a traditional automobile shock absorber support is generally simple in structural design and single in detection mode. The detection equipment comprises a base plate, side supporting plates are vertically welded to the two sides of the outer wall of the top of the base plate, the same top plate is welded to the top ends ofthe side supporting plates, and the two sides of the outer wall of the top of the base plate are fixedly provided with a first tool and slidably connected with a second tool correspondingly. By arranging side ball bodies, the balance weight of a threaded balance weight table block can be further increased, a good anti-skid effect is achieved at the same time, and therefore the threaded balance weight table block can be conveniently disassembled and assembled; a magnetic ring can be in magnetic adsorption fit with the threaded balance weight table block, so that the mounting stability of the threaded balance weight table block is improved, and the safety of detection operation is ensured.

A battery monitor control system has a load plate, two or more lead wires connected to two or more busbars in a string of batteries, and a digital signal processor. The load plate has one or more primary switches connected to two or more terminals of the batteries in the string of batteries. The load plate also has a load resistor and a current sensor. The primary switches are turned on and off to produce a ripple current in the string of batteries. The digital signal processor determines the real portion of the complex impedance of at least one of the batteries by analyzing the voltage and current waveform of the ripple current. The primary switches may be turned on and off with a sin wave modulation.

The invention provides a deceleration strip capable of achieving clear punishment on different vehicle speeds. The upper end and the lower end of the cross section of the deceleration strip are provided with horizontal straight lines, and the two sides of the cross section are provided with a left curve and a right curve which are symmetrical; each curve is composed of a first cosine curve section (1) and a second cosine curve section (2), the first cosine curve section (1) is tangent to the lower-end horizontal straight line, the second cosine curve section (2) is tangent to the upper-end horizontal straight line, and the first cosine curve section (1) is tangent to the second cosine curve section (2). The deceleration strip has the advantages that strong bumping vibration punishment is applied to high-speed vehicles, the higher the vehicle speed is, the higher the punishment intensity is, and therefore a driver is reminded to learn a lesson and dares not to overspeed next time; low-speed vehicles can flatly drive through, and the riding comfort of the driver and passengers is better; the condition that an existing deceleration strip uniformly generates boring vehicle jumping bump and vibration impact no matter the vehicle speed is high or low is changed, induced noise is low, and the service life of vehicle parts and the deceleration strip is prolonged.
