A power source system for a vehicle includes a first power storage device, a second power storage device, a voltage converter, and a controller. The controller is configured to (a) execute a charging control in which the second power storage device is charged by the voltage converter when a parking time of the vehicle exceeds a predetermined period of time, (b) estimate a decrease amount in a state of charge of the first power storage device in a time period from after elapse of the predetermined period of time until a start of the vehicle, (c) set a lower limit of the state of charge based on the decrease amount, and (d) not execute the charging control when the state of charge is lower than the lower limit.

A portable electronic device includes a housing, a plurality of buttons mounted on the housing for operating the portable electronic device, a power supply received in the housing for supplying working electric power to the portable electronic device, and a generator unit. The generator unit includes a plurality of magnetic components mounted on the buttons and a plurality of windings received in the housing and electronically connected to the power supply. Thereby induced currents for charging the power supply are generated when the magnetic components are moved with the movements of the operated buttons.

The invention discloses a clothes tailoring table comprising a work table top and a support bottom frame; the support bottom frame refers to a square bottom frame formed by welding stainless steels; four corners of the support bottom frame are respectively provided with a pneumatic telescoping rod; the top of the pneumatic telescoping rod is connected with the bottom of the work table top; the diagonal intersection point of the support bottom frame is provided with a rotary pedestal; the rotary pedestal is connected with an L-shaped support arm, and the other end of the support arm extends to the outer side; the clothes tailoring table adds the pneumatic telescoping rods on four corners of the tailoring table; a foot-operated controller arranged on one side of the support bottom frame can directly control the height of the tailoring table, thus solving the problems that a conventional tailoring table cannot change the height; the support bottom frame is provided with a seat through the rotary pedestal and the L-shaped support arm, so tailoring people can sit on the seat, thus preventing mass muscle power consumption caused by long time standing up, and reducing tailoring people work intensity.

The invention discloses an accelerated interesting skateboard provided with a pedaling plate, and relates to the technical field of sports apparatus. The interesting skateboard comprises a board surface, a front wheel bracket, the pedaling plate, a connecting rod structure, a rear wheel axle, a rear wheel groove, wheels and a shock absorber, wherein the rear wheel groove comprises a wheel groove main body, a connecting rod rail, a rear wheel axle rail, a small roller and a rear wheel groove spring; the shock absorber comprises an upper support, a piston rod, a spring, a pressure bucket and a lower support; the pedaling plate comprises a pedal surface, spring devices and connectors; and the connecting rod structure comprises a connecting rod I and a connecting rod II. Instead of a boring skating mode of pedaling the ground with foot, a mode of transmitting force by virtue of the pedaling plate provided with the spring devices is adopted to drive the skateboard to get accelerated, so that strength is consumed and body is exercised, and meanwhile, body coordination is trained; by arranging the shock absorber, the circumstance that the skateboard gets bumped on complex pavements is effectively relieved; and on the basis of pedaling strength, the skateboard has the advantages that the skateboard can achieve continuous accelerating and facilitate control, and the skateboard is high in interesting and the like.

A global positioning system (GPS) log with low power consumption has an antenna, a GPS module, a power control module, a main control module, a power adjusting unit and a memory. The main control module is connected to the GPS module and the power control module to retrieve the computing results of the GPS module and controls the power control module to periodically provide power to the GPS module according to a predetermined and variable power providing period. The power adjusting unit is connected to the main control module, analyzes the computing results of the GPS module and assists the main control module to adjust the power providing period. Since the main control module automatically adjusts the power providing period, the GPS log does not deplete unnecessary power on the GPS module. Therefore, the power consumption of the GPS log is reduced and the GPS operates longer.

The invention discloses an undercarriage capable of giving out a deceleration alarm. The undercarriage comprises a fairlead, a mounting base, a threaded connection mechanism, an elastic piece, a mounting sheet, an undercarriage body and a locking apparatus, wherein the mounting base and the locking apparatus are arranged on a rod-shaped component at an interval from front to back; the fairlead is arranged in the front of the mounting base; the upper part of the fairlead is provided with a hole through which a fishline can pass; one end of the elastic piece is fixed to the mounting base by virtue of the threaded connection mechanism, and the other end of the elastic piece is arranged at the lower side of the middle of the mounting sheet; one end of the mounting sheet is rotatably connected to the top end of the threaded connection mechanism, and the other end of the mounting sheet is locked by the locking apparatus; the undercarriage body is arranged on the mounting sheet; the axis of the undercarriage body is vertical to the rod-shaped component; the mounting sheet is further provided with an elastic sheet parallel to the axis of the undercarriage body; the top end of the elastic sheet penetrates through a hub of the undercarriage body; the hole in the fairlead and a neck groove in the undercarriage body are the same in height. The invention also discloses a fishing rod provided with the undercarriage. When fish swims while biting a fish hook and being hung on the fishline, the undercarriage is capable of hindering rapid rotation of the undercarriage body and giving out a sound alarm at the same time.
