Abstract: The present invention relates to communications methods and apparatus for detecting and/or mitigating split brain occurrences in high availability systems. A split brain condition being a condition wherein both a standby processing node and another processing node of a cluster of processing nodes included in a high availability system are both operating at the same time in an active mode of operation. An exemplary method embodiment of operating a high availability system including a plurality of processing nodes includes the steps of determining at a standby processing node that a failure condition exists, said standby processing node being one of the cluster of processing nodes; switching the standby processing node from a standby mode of operation to an active mode of operation in response to determining that a failure condition exists; and determining whether the high availability system is experiencing a split brain condition.

Abstract: A sensor assembly includes an electrically conductive electrode bridge (26) and a multi-layer, integral sensor body (1). The sensor body (1) includes a core layer (2), an outer insulating layer (4) that substantially surrounds the core layer (2), and an electrically conductive electrode layer (6) between the core layer (2) and the outer insulating layer (4). The sensor body (1) also includes an electrically conductive electrode interface layer (14) at a rear part (12) of the sensor body (1) and in electrical contact with the electrode layer (6). The electrode bridge (26) is held in compression electrical contact with the electrode interface layer (14) during use.

Abstract: A sling strap retention device is provided. The sling strap retention device includes a structure with a first flexible member and a second flexible member, the first flexible member and the second flexible member further comprising a first end and a second end, a first side and a second side, a front surface, and a back surface, wherein the first and second flexible members may be oriented one over the other with the back sides of the first and second flexible members in opposition and coupled along a length of the members. The first and second flexible members may be configured to flex and couple to one another to form opposing closed loops. These closed loops may be configured to couple to and retain therein a sling strap of a weapon.

Abstract: The invention provides a container for storing and dispensing consumer products and can be used in place of conventional blister packs for the packaging of pills, tablets or capsules or multi-cavity containers for organising and storing mixed medication for subsequent dispensation according to a predefined dosage regimen. The container includes a tray (1) having a generally planar top surface (2) into which has been formed one or more discrete cavities (3) for receiving the consumer products. A sheet (10) is adhered to the top surface (2) of the tray (1) using a peelable adhesive to seal the one or more cavities (3). The sheet (10) has pre-formed tear lines (13) defining a tear off portion (12) per cavity (3) to retain the consumer products in that cavity until it is removed by tearing along its tear lines. The or each tear-off portion (12) has low vapour transmission properties created by a patch (24) with high vapour barrier properties.

Abstract: Preparation of polyurethane foams using 1,1-dichloro-2,2,2-trifluoroethane as a blowing agent eliminates the need for stabilizers in component mixtures.
