A ride surface for water ride attractions and the like is provided. The ride surface is fabricated from a reinforced membrane material tensioned over a supporting framework. The tensioned membrane ride surface serves the dual role of providing structural support for water flow and riders thereon while at the same time providing an impact safe surface that is non-injurious to riders who may fall thereon. The tensioned membrane can be adjusted actively and/or passively in order to accommodate different and varied ride experiences. Optionally, the shape of the membrane ride surface can be changed either dynamically or passively by special tensioning techniques and/or by using auxiliary support structures such as air bladders, pressure/suction, foam supports or/or the like.

A system and method for dynamic device configuration enabling network and security administrators to define policies that indicate event and alert conditions within their networks. The policies incorporate information about network devices, endpoints connected to those devices, input from external security systems, local endpoint policy compliance, and date/time-of-day to determine whether to generate an event or alert. Events and alerts can be associated with actions that effect changes to network device configurations in order to maintain a desired operational state of the network.

A yoga block in the preferred embodiment of the present invention is a prism-shaped triangular block that provides a stable and solid base on all sides, horizontally and vertically, and is equipped with ergonomically placed hand grooves and multiple level hand slots for tailored use. A yoga block that is prism-shaped and triangular can benefit beginners and advanced yoga practitioners alike in the journey to refine their practice through safe and proper alignment various yoga postures. Furthermore, the present invention in the preferred embodiment is enhanced with large slots at differing height levels, which allows for easy and accurate tracking of improvement and personal goals, creating a truly multi-functional, cost-efficient item for manufacture. A yoga block in the preferred embodiment is preferably composed of lightweight yet sturdy materials such as: foam, cork, or natural wood, but is in no way limited to these suggested materials.

A support structure for a roller for a shade includes a bracket, a plug and a limit member. The bracket is adapted to fix on a fixing member, and includes a connecting hole. The plug has one end connected to a shaft tube of the shade, and the other end thereof is inserted into the connecting hole of the bracket. The limit member is connected to the end of the plug, which is provided for being inserted into the connecting hole of the bracket, whereby the limiting member restrains the plug from detaching from the bracket. By the limit member, the connection of the bracket and the plug could be strengthened, so as to prevent the shade from falling off, whereby to enhance the safety of the support structure for the shade in use.

A rotobaler is provided with an inclination sensor that recognizes an inclination to the side as well as in the longitudinal direction. This inclination sensor generates a signal coupled to a computer that, in turn, controls a display arrangement in order to indicate whether a base that is to be unloaded from the rotobaler can be safely unloaded considering the existing inclination of the rotobaler. In the event an unsafe inclination is present, either the computer sends out a control signal which blocks an operation for depositing the bale on the ground, or causes the bale to be oriented in such a way during the discharge process that the longitudinal centerline of the bale is parallel to the inclination of the slope.

A transport truck that can be used to safely move various articles of furniture, including heavy stacks of differently configured chairs from one location to another. The transport truck includes specially configured article support members and assemblies that can be affixed to the base of the transport truck to safely transport various kinds of furniture from auditoriums, conference rooms and like to storage areas.

A weightlifting apparatus that supports a free weight barbell when activated using two counter-weight controlled support arms that are mechanically attached to a vertical support on a bench press system. The vertical supports each have a slide rail that is mechanically coupled to a locking assembly that acts to release the support arms using buttons. The support arms are attached to independent counterweights or springs by means of a cable. When released by a foot pedal these support arms are elevated by the counterweights. The support arms hold the barbell and prevent it from downward movement via the one-way locking assembly mounted to the support arms. The support arms work independently of one another so that a user may reset each support arm independently.

An apparatus for supporting pot covers includes a frame movable between a collapsed position and an expanded position; a support for resting the frame on a surface and at least one pot cover support pivotally connected to the frame. The pot cover support further has a leg pivotally engaging the frame, a pot cover knob support and a pot cover handle support.

A pet booster seat to be secured to a generally vertical vehicle seat back is configured to support a pet elevated above a horizontal vehicle seat cushion. A basket assembly is formed by a rod configured to form an upper basket frame and a rectangular basket, having front and rear panels and right and left side panels, each of the panels being folded and sewn to form a casing envelope around the upper periphery of the basket for encasing the upper basket frame. The basket assembly is pivotally connected to a backboard having upper and lower edges and right and left side edges. Two support rods having lower ends pivotally secured to the backboard extend from adjacent a lower edge of the backboard upwardly to the upper basket frame. A pair of tubes is pivotally secured to the upper basket frame and telescopically receive upper ends of the support rods such that the support rods are aligned to the internal wire frame to stabilize the basket from below to provide an unobstructed view and a comfortable ride for the pet.

A baby carrier includes an infant harness and an adult harness joined in sliding engagement enabling horizontal rotation of the infant harness relative to the adult harness. The position of the baby harness may be set at any selected point of rotation. The harnesses are fully adjustable to fit both the baby and the adult and are made of a water compatible material such as that used for swimsuits. The carrier is useful in both pool and shower for supporting the baby safely.

The invention relates to a method for constructing an underground coal mine chamber, in particular to a method for constructing an underground coal mine chamber of large cross section, aiming at solving the problem that the prior method for digging and blasting the underground coal mine chamber of large cross section has low efficiency. The method for constructing the underground coal mine chamber of large cross section comprises the following steps: a, selecting an area having gangue on the upper layer and coal on the lower layer to construct the underground coal mine chamber; b, digging and blasting the upper layer of the area; c, breaking the large gangue generated from digging and blasting the upper layer of the area into pieces; and d, cutting the coal in the lower layer of the area with a fully-mechanized coal winning machine and conveying the coal and the broken gangue out. The method for constructing the underground coal mine chamber of large cross section integrates the digging by blasting with the digging by the machine, omits the procedures of perforating the coal layer, blasting and the like, effectively increase the production efficiency, reduces the labor intensity of the worker, adopts the machine unit to cut the coal layer, causes less vibration to the coal side, obviously improves the forming and supporting effect and ensures the safety of supporting two sides of the high tunnel.
