Abstract:
A power conditioning circuit for use in a power supply includes a power input and a power output. The circuit also includes a series connected RFI-EMI filter, rectifier, and SCR between the power input and the power output. The SCR has a control input for switching the SCR on and off, thereby interrupting current flow between the power input and the power output. An energy storage circuit is connected across the power output. Furthermore, the circuit includes a control circuit coupled to the control input of the SCR for switching the SCR on and off to maintain a regulated voltage at said power output in response to an AC input. A conditioned DC output is produced in response to a DC input.
Abstract:
An I/O device in the form of an internal dongle (79) includes a body (96) having connective structure being arranged to removably attach the body (96) to a housing of an electronic device. The dongle (79) also includes a circuit assembly that has an exterior connector (102) on the body (96) for electrically connecting to a second electronic device, a dongle circuit (104) being electrically coupled to the external connector (102) through the body, an electronic cable (106) having a first end electrically coupled to the dongle circuit (104), and a second end (108) being structured and arranged to connect to an electronic component of the first mentioned electronic device within the housing.
Abstract:
An industrial computing device that is expandable by the use of expansion modules. The industrial computing device includes a field mountable housing having a primary housing (70) and first and second side covers (68, 66). The processor (22) is internal to the housing and the first side cover (68) allows access to the processor (22). At least one peripheral connector (94(1), 94(2)) adapted to receive at least one PCMCIA card (95) is internal to the housing. The peripheral connector (94(1), 94(2)), the primary housing (70), and the side covers (66, 68) being oriented orthogonal to a mounting plane of the industrial computing device.
Abstract:
A Keypad Annunciator Graphical User Interface, (KAGUI), for use by an operator of a process control system for presenting and responding to alarm state data generated by the process control system, is disclosed. The KAGUI provides an interactive display of a keypad annunciator on a monitor display screen. A panel manager display and a dynamic icon enhance operator awareness, in a multi-window display environment, of alarms. The KAGUI synchronizes alarm data presented by the KAGUI with process control system alarm data and informs the operator of the status of interprocess communication.
Abstract:
Methods and apparatus for the concurrent display of two or more property pages of a Graphical User Interface (GUI) are disclosed. A user can select a property page displayed by a first property sheet system and create a second property sheet system that displays the selected property page at second, user selected display position. Alternatively, the user can place, or dock, the selected property page into an existing property sheet system for inclusion therein and display thereby. The first property sheet system displays, at a first display position, any of the property pages remaining therein. Typically, the selected property page is removed from the first property sheet system and the first property sheet system is destroyed if it contains no other property pages. The invention allows a user of a GUI to concurrently display and interact with multiple property pages of multiple property sheet systems for optimizing the exchange of information with the GUI.
