An energy storage system is provided. The system comprises an energy storage device comprising: a pressure vessel configured to store pressurised fluid; and one or more resilient elements, wherein the resilient elements comprise a plurality of filaments of resilient material braided to form the resilient elements, wherein the resilient elements are arranged within or about the pressure vessel, and wherein the energy storage device is configured such that storing pressurised fluid within the pressure vessel acts to tension or compress the resilient elements.

A foreign substance removing device includes: a cylinder including a support portion; a piston configured to send out a fluid flowing into the cylinder; a spring configured to urge the piston; and a mechanism configured to apply a moving force to the piston. A direction in which the fluid is sent out is a first direction. The piston is moved in the first direction by an urging force of the spring. An operation portion of the piston is formed with a convex or concave portion. The support portion is formed with an insertion concave portion into which the convex portion is capable of being inserted or an insertion convex portion capable of being inserted into the concave portion. A compression space is formed in the moving space when the piston is moved in the first direction and the convex portion or the insertion convex portion is inserted.

This invention generally relates to pull back toy cars. Specifically, this invention discloses mechanisms relating to uses of a gearbox contained inside an wheel assembly in order to create vibration sensitivity to enhance user experiences. More specifically, the unique feature of placing more than one gearbox in the wheel assembly offers the pull back toy car with more variety in terms of play style, including a wheel-like pull back toy car, a two-wheel pull back toy car with various levels of vibration set by a user. Further, this invention includes the user of a handle attached to a gearbox so that the location of the gearbox placed within the wheel assembly can be changed so that the level of vibration of the wheel assembly or the toy vehicle can also be adjusted freely by the user.

A device for switching medium and/or high voltages has a spring-loaded drive for driving a kinematic chain. At least one energy storage spring and at least one damping element for generating a drive movement with specific drive characteristics are included. The at least one damping element is an active damping element. The damping is actively determined during switching or it is predetermined, in particular depending on environmental variables and/or the type of switching situation, by changing the settings of the at least one damping element.

According to embodiments of the disclosed technology, systems and methods are provided for a mobile gateway I.T. system that is configured to receive a message from a source for transmission to a destination and multiple varying communication channels on which to transmit the message to the destination. The system may use a logic control library that is tightly coupled to the mobile gateway and the communication channels. The logic control library may be configured to select a first communication channel from the communication channels to route the message for transmission to the destination. The logic control library may be further configured to select a second communication channel from the communication channels to route the message for transmission to the destination in response to a period of time expiring without receiving a confirmation protocol from the destination via the first communication channel.
