A content channel is periodically or permanently allocated for use as an “update channel” or “firmware-image download” channel. Any firmware images downloaded to receivers in the system are thoroughly tested prior to being distributed among the receivers. Header information is included in the firmware image when it is transmitted to the receivers, and the firmware image is not accepted for use by the receivers until it is verified on the receiver side. Further, rather than overwriting the existing firmware, the new validated firmware updates are stored separately on the receivers and are utilized when the receiver is rebooted during power-up or by the host controller. If, during this reboot process, an error occurs in the new firmware image, the receiver is configured to revert back to the original firmware image so that it will remain operational, albeit without the updated firmware features.

An air compressor assembly includes a compressor configured to provide a source of compressed air and a manifold assembly removably coupled to the compressor and configured to distribute the compressed air to one or more pneumatic tools. The manifold assembly is configured to be coupled to the compressor via an air conduit when the manifold assembly is detached from the compressor so that the manifold assembly is operable at a location remote from the compressor.

A trash bag holding stand that may be manually assembled without the use of tools to support a pliable bag (such as a plastic bag) in open fillable position.The stand includes a rectangular frame with its corners formed of right angle pipe elbows having sockets disposed at right angles to each other. The sides of the frame are elongated members such as pipes which are telescoped into the respective sockets of the elbows to form the frame. The elbows also have leg-receiving sockets into which legs are telescoped to support the frame. Upstanding pins are disposed on the top surface of the elbows for detachably receiving the plastic bag. The stand may be provided with a cloth bag for receiving the plastic bag to protect it from breaking. A funnel may be provided to facilitate flow of waste material into the plastic bag.

Apparatus and a method for a client/server computing system having an optimized log file system for replaying client disconnect write operations to a server when the server becomes available to the client. Data in the unauthorized disconnect write operations to a target file at the client are prevented from being copied to the server when the server becomes available. When there is a write request for a target file at the client, and the client detects the target file has already been written, the credentials with the write request are compared to the store credentials from a previous write to the same target file. If the request credentials are the same as the stored credentials, data from the write request is written to the target file effectively adding more data to the target file. If the request credentials are not the same as the stored credentials the write request is suspended at the client. When the client detects that the server is available, the stored credentials of the target file are retrieved from the credentials table, and the target file is sent along with the stored credentials to the server.
