Abstract: A method is provided for calculating an amount of guarantee deposit of a supplier, comprising: providing a server, in which stores a standard guarantee deposit rate table, a defect rate table, a standard defect rate table, a materials table recording a quantity and a unit price of each type of materials; obtaining a standard guarantee deposit rate from the standard rate table; determining a coefficient of the guarantee deposit by obtaining a defect rate and the standard defect rate of the materials respectively from the defect rate table and the standard defect rate table; determining an actual guarantee deposit rate of the materials according to the standard guarantee deposit rate and the coefficient; and calculating an amount of guarantee deposit according to the actual guarantee deposit rate and a quantity and a unit price of the materials obtained from the materials table.

Abstract: A display device includes a detachable housing, a main body, and an interface unit. The interface unit electrically connects the detachable housing with the main body. The detachable housing includes an OSD unit for storing a plurality of OSD data; a command input unit for generating and sending signals in response to operations of a user; a processing unit for identifying operations of the user, and, if required by the operations, performing predetermined function to obtain OSD data, generating a corresponding control signal, and transmitting the OSD data and the control signal to the main body through the interface unit. The main body displays an OSD menu corresponding to the OSD data and adjusts the parameters of the display device, corresponding to the control signals.

Abstract: A display device includes a main body and a housing. The main body includes a control unit. The housing includes a command input unit associated with the housing. The command input is replaceable piece of equipment. The command input unit includes a plurality of pins for generating the control signals in response to operations of a user, each of the pins being designated with an identifier. The number of pins is dependent on the particular command input unit selected by a user. The control unit identifies the control signals and performs the corresponding functions through the identifiers. The functions include turning on the display device, turning off the display device, obtaining corresponding OSD data, displaying an OSD menu, and adjusting parameters of the display device.

Abstract: A remotely switchable circuit breaker mounted in the casing of an electrical device comprises a circuit breaker unit, provided with a switching paddle, and a remote switching mechanism connected to the switching paddle. The remote switching mechanism comprises a connecting rod that pivotally connects a remote switch and rotatably and slidably connects the paddle. The remote switch, including a key button, is pivotally fastened with the casing via a first fastening base. The connecting rod is further rotatably and slidably fastened with the casing via a second fastening base. A pressing action on the key button causes a rotation and slide of the connecting rod that actuates a switching movement of the paddle of the circuit breaker unit.
