摘要:
The invention relates to hybrid fuel cell systems that protect a fuel cell with a second electrical energy source. The second electrical energy source powers a load to prevent the fuel cell from witnessing stoichiometric levels that may lead to reductions in fuel cell performance or health. The hybrid fuel cell system includes an electrical circuit that electrically initiates the electrical energy source to provide power to the load in response to detecting a potential stoichiometric disturbance for the fuel cell.

In one embodiment, a method can include providing first and second intermediate structures, each having first and second surfaces. Also, the method can include placing the first surface of the first intermediate structure adjacent to the first surface of the second intermediate structure, such that the first and second intermediate structures are in a stacked relationship. Additionally, the method can include simultaneously removing at least a portion of each of the second surfaces of the first and second intermediate structures while in the stacked relationship. Furthermore, the method can include forming a plating layer on each of the first and second surfaces of each of the first and second intermediate structures. Moreover, the method can include forming a magnetic layer on the second surface but not the first surface of each of the first and second intermediate structures.

In one embodiment, a mounting bracket for mounting a horizontal support member between vertical support columns of an equipment rack. The mounting bracket comprises a base member and a latch. The base member comprises integrated side and end plates, with the side plate being securable to the horizontal support member and the end plate constructed to vertically support the mounting bracket thereon. The latch detachably adjoins the mounting bracket to the vertical support column, and is constructed to be hand-operated to detach the mounting bracket from the vertical support column in response to a tool-less manual manipulation of the latch.
摘要:
A base includes apertures and surface features for precisely aligning central processing units (CPUs) and jackets with each other. Applicator heads are used to exert contact force against respective jackets during adhesive bonding to the CPUs. Each jacket functions as a gripping or handling feature during subsequent positioning or transport of the corresponding CPU. Such CPUs can be inserted into servers or other entities by way of automated mechanisms or manual operations with reduced risk of damage, misalignment or other problems.

A computer comprising a chassis supporting an electronic component. A fan housing with an axial duct is mounted to the chassis. A blade assembly is rotatably disposed within the duct and comprises a plurality of fan blades that extend radially from a hub to a fan diameter. The axial duct has a chord length at least equal to the fan diameter.

In operational environments where local loop generation equipment is used, communication interruptions between a central office and a customer premises device is minimized by using a dedicated communications link between the local loop generation equipment and the central office. A processing mechanism at the central office determines if, when, and under what circumstances the customer premises device will be notified in response to the activation of local loop generation equipment. This eliminates the need to place local loop generation equipment in series with a communications path that runs between the central office and the customer premises. The central office may provide the dedicated communications link in the form of a telephone line which is equipped to place outgoing local calls, but not equipped to receive incoming calls, and not equipped to place long-distance calls.

According to one embodiment, the present invention includes a first electrical connector located on a computer component and a biasing mechanism having a leverage member, such that actuation of the leverage member biases the first electrical connector between engaged and disengaged positions with respect to a second electrical connector separate from the computer component.
摘要:
A precise adjustment indicator holder in which a position indicator is carried with respect to a work tool and a work piece. The indicator holder connects to the quill of the work tool, such as a machine tool, or other supporting device and is comprised of a pair of arms which are pivotally connected to one another and movable in planes parallel to and relative to one another. The arms are provided with abutments to limit the degree of movement such that precise final adjustment of the positioning of the work tool can be achieved.
