  • Publication number: 20260069912
    Abstract: A mounting system for attachment exercise machine accessories wherein the mounting bracket is a separate piece that can be attached to the exercise machine prior to mounting of the accessory on the mounting bracket. The mounting bracket can be adapted to mount to existing exercise machines, and is easy to attach to an exercise machine separately from accessories to be mounted on it. The mounting bracket facilitates attachment of interchangeable accessories through a simplified mounting system that allows the user to keep both hands on the accessory during mounting. Play in the interface between the mounting bracket and accessory is taken up by a tensioning and locking device.

  • Publication number: 20250325867
    Abstract: An exercise machine that combines the functionality of a leg press exercise machine with the functionality of a hip thrust exercise machine in a single machine. In an embodiment, the exercise machine comprises an adjustable exercise bed comprising an adjustable backrest and a lockable, pivoting seat; a weight plate holder; a footpad having different angles for leg presses and hip thrusts; and an incline adjustment mechanism. The exercise machine can be converted from a leg press machine to a hip thrust machine by changing the position and settings of the adjustable backrest and lockable, pivoting seat.

  • Publication number: 20250319347
    Abstract: A portable platform accessory for linear-pull weight machines which allows a user to engage in a variety of vertical resistance exercises at a distance away from a linear-pull weight machine at a location convenient for the user. This accessory allows for addition of belt squats, dead lifts, bicep curls, and other vertical resistance exercises on linear-pull weight machines that do not come equipped with those exercises or for which performance of those exercises close to the linear-pull weight machine is inconvenient. Further, due to its portability, this accessory can be placed in a variety of locations at a distance from the linear-pull weight machine, adding belt squats, dead lifts, bicep curls, and other vertical resistance exercises even where the linear-pull weight machine is in confined spaces where these exercises could not otherwise be performed or would be inconvenient due to space restrictions.

  • Publication number: 20180135979
    Abstract: Provided is a switching cap having a plate and a block formed on the plate. Also provided is a mode-switchable rangefinder having a protection component, a housing, a binocular module, a display module, a circuit board with a photoelectric switch, a distance sensor module, and a slope sensor module. The four modules and the circuit board are disposed in the accommodation space, and the display module, the distance sensor module, and the slope sensor module are electrically connected with the circuit board. When the switching cap is in use, the block is disposed between two ends of the photoelectric switch, such that only distance information is displayed for tournament. When the protecting cap is in use, the ends of the photoelectric switch would not be isolated, such that both distance and slope information can be displayed for practice.

  • Publication number: 20140059511
    Abstract: Aspects of the invention relate to yield analysis techniques for generating root cause candidates for yield analysis. With various implementations of the invention, points of interest are first identified in a layout design. Next, regions of interest are determined for the identified points of interest. Next, one or more properties are extracted from the regions of interest. Based at least on the one or more properties, diagnosis reports of failing devices fabricated according to the layout design are analyzed to identify probable root causes.

  • Publication number: 20080091487
    Abstract: A method of evaluating advertising expenditures includes establishing a first relationship between advertising position and bid price. A second relationship between estimated expenditure per time period and bid price is formed. An average advertising position for an entity is observed. A frequency of appearance for the entity is located. The average advertising position is mapped to a bid price using the first relationship. The bid price is mapped to an estimated expenditure per time period using the second relationship. The average expenditure is multiplied by the frequency of appearance to establish a per time period expenditure for the entity.

  • Publication number: 20070120673
    Abstract: A system federates heterogeneous monitoring systems to provide end-to-end monitoring information for conveyances with item-layer visibility. A first node of the federated system comprises a first monitoring system and a first port and a second node comprises a second monitoring system and a second port. In parallel with a conveyance being transported between the first node and the second node, the first monitoring system sends an agent to the second monitoring system. The agent comprises logic and/or data necessary to implement processes on the second monitoring agent while the conveyance is at the second port. When the conveyance arrives at the second port, the second monitoring system executes the agent to determine conditions of the conveyance and/or its contents.
