Various electrically controlled devices of a bicycle are electrically coupled together by multi-conductor electrical cords. Preferably, the ends of the electrical cords have an electrical connector that mates with a corresponding electrical connector of an electrically controlled device. The electrical connectors are designed to be coupled together by a snap fit. Each electrical connector attached to the end of the electrical cord has an electrical contact housing with electrical contacts and an outer casing molded about the electrical contact housing to form a tubular portion radially spaced from the outer end of the electrical contact housing. A retaining ring is located in an annular groove formed in an exterior surface of the outer casing to provide an additional coupling force. Preferably, an annular sealing member formed of a resilient and compressible material is located in an annular space formed between the tubular portion and the electrical contact housing.

With an information processing apparatus, if a user operates a “back” button of a web browser while a job is being executed, a script for controlling the job currently being executed is lost, and the job can no longer be controlled. An information processing apparatus of the present invention can communicate with a web server, and includes a web browser that displays an operation screen provided by the web server. This information processing apparatus manages the status of a job to be executed, and restricts acceptance of an instruction for screen transition from the user according to the managed status of the job while the job instructed by the web server is being executed.

An apparatus for aiding mobility of a user comprises inner and outer shafts each having a grip projecting transversely therefrom. The inner shaft is receivable in the hollow outer shaft and a locking mechanism is provided for securing the inner shaft in fixed relation to the outer shaft in a manner providing a plurality of configurations of the apparatus. Generally speaking, the configurations of the apparatus include a nested configuration in which the inner shaft is substantially entirely received in the outer shaft so as to present the grips in close proximity to one another, and an extended configuration in which the inner shaft projects along an axis of the apparatus beyond a top of the outer shaft so that the grips are in axially spaced relation. The inner and outer shafts may also be separated so that each forms a separate cane for use in one hand of the user.

The invention aims to provide a longitudinal movement attitude control device for a catamaran. The longitudinal movement attitude control device comprises a deck. A first sheet and a second sheet are respectively mounted at the left end and the right end of the lower side of the deck, a first front strut and a second front strut are respectively mounted at the front end of the first sheet and the front end of the second sheet, a first rear strut and a second rear strut are respectively mounted at the rear end of the first sheet and the rear end of the second sheet, a front hydrofoil is mounted at the lower end of the first front strut and the lower end of the second front strut, a rear hydrofoil is mounted at the lower end of the first rear strut and the lower end of the second rear strut, a first flap and a second flap are respectively arranged at the rear end of the front hydrofoil and are connected with the front hydrofoil by a first transmission shaft, a third flap and a fourth flap are respectively arranged at the rear end of the rear hydrofoil and are connected with the rear hydrofoil by a second transmission shaft, and the first transmission shaft and the second transmission shaft are respectively connected respective servo systems. The longitudinal movement attitude control device has the advantages that a heeling angle of the catamaran during pitching / heaving movement and rotation can be effectively reduced when the catamaran sails at a high speed, and accordingly the stability of the catamaran is improved.

The invention discloses an active control method for helicopter vibration based on adaptive harmonic recognition frequency response correction. In order to solve problems such as the decline of control effect or even control divergence, an adaptive harmonic identification algorithm is proposed to correct the parameters of the frequency response function of the control system in real time according to the harmonic coefficient of the control error response signal, so as to realize the comparison of the helicopter modeling error. The purpose of actively controlling the vibration of the helicopter under severe conditions. This method has the advantages of high frequency response estimation accuracy, fast control convergence, small calculation amount and no need for additional excitation. It can achieve high efficiency, strong adaptability and fast convergence control effect when the modeling error is large.
