This invention relates generally to security covers for electrical appliances which are powered by mains electricity. More specifically it relates to security covers to operate the electrical appliances by authorised users locally or remotely via an authorisation device via a network such as the internet. The security cover houses a switch and includes an authorisation device for enabling an authorised person to control a power supply, via the switch, to an electrical device or appliance. The security cover has an input means adapted to receive an authorisation signal; the switch is operative in response to the authorisation signal and a command signal in order to connect and disconnect the power supply to the device or appliance.

The invention concerns a battery system (200) for a vehicle (1), preferably for an industrial truck, comprising: at least one rechargeable battery (210) for supplying at least a vehicle component (2) of the vehicle (1), a charging component (50) for mechanically (52) and electrically (53) charging connection with an external charging device (310) to charge the battery (210) through the charging device (310) in a state of charge, a safety device (60), which is arranged at least partially in the area of the charging component (50), for detecting the mechanical charging connection of the charging component (50) with the charging device (310), so that a safety interruption of the power supply of the vehicle component (2) can be performed in the charging state.

A plug socket includes a recess receiving a charging plug in a plug-in direction and a locking element movable from a plug-in position into a blocking position. The recess terminates in an insertion opening in the plug-in direction and has an undercut acting in the plug-in direction to latch a latching element of the charging plug. The locking element in the plug-in position is located in the recess and overlaps the undercut transverse to the plug-in direction. The blocking position is spaced apart from the plug-in position in the plug-in direction and the locking element is located closer to the insertion opening in the blocking position than in the plug-in position.

An actuator is provided that is smaller in size and has a simpler structure, as compared with a conventional one. The actuator is composed of a driving mechanism that includes an electric motor, and a housing that houses the driving mechanism. The housing includes an air hole that communicates the inside of the housing with the outside thereof, a filter that covers the air hole, and a motor box that surrounds the electric motor. At least one of members of the motor box acts as a scattering prevention wall that prevents lubricant from scattering to the electric motor. The air hole is formed in a member of the motor box other than said at least one of members of the motor box.

A power connector with an anti-disengaging mechanism that has a power socket that includes a metal terminal. The power socket is shaped to receive a plug pin of a power plug. A seizing piece that includes a through hole. The seizing piece is located so that the plug pin of the power plug travels through the through hole in order to come in contact with the metal terminal. A pull rod is arranged so that when the pull rod is in a first position, the pull rod tilts the seizing piece so as to lock the plug pin in contact with the metal terminal. When the pull rod is in a second position, the seizing piece releases the plug pin. A toggle ring is rotated by a user to drive the pull rod to slide between the first position and the second position. A first portion of the seizing piece is within a supporting groove inside the power connector. A second portion of the seizing piece is inserted into a driving groove of the pull rod. Movement of the pull rod is controlled by the toggle ring.

A locking element for use with a cable having a plug insertable into a plug receiver of a housing is provided. The locking element includes a connector body connected to the plug and including a receiving feature insertable through an aperture of the housing. The locking element further includes a locking feature configured to assume one of a locked condition in which the locking feature locks onto the receiving feature or prevents insertion of the receiving feature through the aperture and an unlocked condition in which the locking feature unlocks the receiving feature or permits insertion of the receiving feature through the aperture and an actuator coupled to the locking feature and configured to control the locking feature to assume the one of the locked and unlocked conditions.

A system is provided. The system includes a computing resource, a cable insertable into the computing resource, a locking element and a controller. The locking element is configured to assume a locked condition in which the cable is locked to the computing resource or prevented from insertion into the computing resource and an unlocked condition in which the cable is removable from the computing resource and permitted to be inserted into the computing resource. The controller is configured to define rules for users. The rules are associated with respective identifiers (IDs) of each of the users and establish criteria associated with each user for causing the locking element to assume one of the locked and unlocked conditions.

A system is provided and includes a securable resource, a locking element configured to assume a locked condition in which the securable resource is locked and an unlocked condition in which the securable resource is unlocked, a first controller, which is receptive of an instruction to authorize users to unlock the securable resource, and a common interface to which the first controller and additional controllers, which are independent from the first controller and one another, are tied. The first controller is configured to authenticate the users and to perform operating system (OS) level control of the locking element in accordance with the instruction to authorize users and an authentication of the users by the common interface.

A system is provided and includes a resource, locking elements and a controller. The resource includes multiple independently securable resources. The locking elements are respectively configured to assume a locked condition in which corresponding ones of the multiple independently securable resources are locked and an unlocked condition in which the corresponding ones of the multiple securable resources are unlocked. The controller is receptive of an instruction to authorize users to unlock the one or more of the multiple independently securable resources and is configured to perform operating system (OS) level authentication of the users and OS level control of the locking elements in accordance with the instruction to authorize users and the OS level authentication.

A system is provided and includes a securable resource, a locking element configured to assume a locked condition in which the securable resource is locked and an unlocked condition in which the securable resource is unlocked, a controller and a physical authentication interface. The controller is receptive of an instruction to authorize users to unlock the securable resource and configured to perform operating system (OS) level authentication of the users and OS level control of the locking element in accordance with the instruction to authorize users and the OS level authentication. The physical authentication interface is configured to enable or disable a capability of the controller to perform the OS level authentication.
