Abstract: This invention is a tamper evident container having a base and removable lid comprising a pull tab and a lid surface, wherein the base and lid fit together with an interference fit. The pull tab extends toward the center of the lid surface and away from a base portion of the pull tab, the base portion being located at an edge of the lid. The pull tab further comprises a pull tab portion having a first side that is attached to a first tab marker by a first frangible line, and a second side that is attached to a second tab marker by a second frangible line. The pull tab portion overlays at least one detent that marginally biases the pull tab portion away from the lid surface.

Abstract: This invention relates to a tamper evident container comprising a base, a lid, and a tab, wherein the lid has a hidden edge seated on the base and tab is a separate article that is bonded to the lid. The tab is preferably used to demonstrate overt evidence of tampering with the container and to disengage the lid from the base. In a preferred embodiment of the present invention, the tab is bonded at first and second tab portions on a lid surface near a middle lid edge of the lid. The second portion of the tab comprises a bonded tab marker and a bridge. When the tab is pulled away from the lid, the bonded tab marker breaks away from the tab at a frangible line, and remains bonded to the lid as evidence of tampering with the container. Absent the marker, the boundaries of the bridge define a finger hole in the tab that may be used to unseat the lid from the base.

Abstract: An electrical pressure washer includes a diagnostic circuit for detecting operation conditions that may affect the normal operation of the pressure washer, and a plurality of indicators indicating the detected operation conditions, such as ground fault, low pressure, overheating, etc. A voltage drop across the power cord of the pressure washer is monitored and used to identify several of the operating conditions. A way of connecting and controlling light-emitting diodes used as indicator lights is provided to allow energy-efficient operation of the indicator lights.

Abstract: A method is described that can be used to communicate information among a group of participants. A participant may create an electronic form specifying a list of network addresses corresponding to other participants intended to receive the communication. A server receives the form and delivers a message associated with an electronic medium. When the participant opens the message, the electronic medium is produced by the server and includes static and dynamic content. The participant can add content to the dynamic content. The dynamic content may be asynchronously dynamically updated in the server to indicate a then current content of the electronic medium, and can be accessed by other to participants in the group.

Abstract: An electronic medium is described that can be used to communicate information among a group of participants. The electronic medium includes a transport envelope having a plurality of network address. An encoding layer may be contained in the transport envelope to support a plurality of content-types. Each of the plurality of content-types may include a plurality of dynamic and static content. An interface region may be configured in the electronic medium to accept input from at least a user of the electronic medium or from an external source in data communication with the electronic medium. The dynamic content may be dynamically asynchronously updated based on the input from at least the user or the external source.
