  • Patent number: 11989387
    Abstract: A computing device displays a user interface for a data preparation application, including a flow pane that visually represents a data preparation flow and a plurality of icons in a flow element palette. Using a feature/version matrix, the device determines that (i) a first subset of parameterized operations represented by a first subset of icons is not supported by the data preparation server application according to a version number of the data preparation server application and (ii) a second subset of parameterized operations represented by a second subset of icons is supported by the data preparation server application. The device provides a first indication that the parameterized operations represented by the icons in the first subset are unavailable to be inserted into the data preparation flow and displays a visual indication that each of the icons in the second subset is available to be inserted.

  • Publication number: 20240125152
    Abstract: An anti-theft device for securing an article of merchandise against unauthorized removal from a display counter. The anti-theft device comprises a latch plate and a pedestal having a quick-release interface. The latch plate is configured to selectively couple to the quick-release interface. A latch bolt is disposed within the pedestal. The latch bolt locks the latch plate relative to the quick-release interface. A plurality of retaining arms is configured to receive and retain an article of merchandise. The retaining arms cannot be disengaged from the article of merchandise while the latch plate is locked relative to the quick-release interface. A solenoid is housed within the pedestal and operationally connected to the latch bolt. The solenoid is configured to retract the latch bolt into a position in which the latch bolt disengages the latch plate, thereby releasing the latch plate from the quick-release interface.

  • Patent number: 10099532
    Abstract: An environmental control system for a battery in a vehicle includes an air intake for receiving ambient air from outside the vehicle. A duct system provides communication between the air intake and the battery. The duct system includes a movable door which can facilitate or inhibit movement of air between the air intake and the battery. An air outlet facilitates air flow from the duct system to the ambient environment outside the vehicle. A fan cooperates with the duct system for moving the air through a heat exchanger in the duct system and across the battery. A control system controls operation of the fan and the movable door, and is configured to determine whether the battery environment requires fresh air or recirculated air.

  • Patent number: 8569656
    Abstract: A heater system for an electrical storage device, such as a high voltage traction battery, is connectable to an external AC power source maintain a proper temperature of the battery as long as the system remains connected to the external power source. The battery temperature can be maintained at a level that ensures that the vehicle will start even in extremely cold climates. The heater system includes a heater disposed within the battery itself. Other system components, such as an AC/DC converter and a control module, may be connected to the battery heater system outside of the battery, allowing the battery heater system to act as a modular component that can be easily included in or excluded from a vehicle as an option, either alone or in a package with an engine block heater. The battery heater system is designed so that it can be connected along with the engine block heater to the AC power source using a single common connector.

  • Patent number: 7607501
    Abstract: A cooling system for a battery in a vehicle does not use air from the vehicle passenger compartment, but rather, takes in ambient air from outside the vehicle. When the temperature of the ambient air outside the vehicle is low enough, the air is moved through a duct system by a pair of fans and blown across a battery assembly. When the temperature of the ambient air outside the vehicle is too warm to cool the battery directly, it is first passed through an evaporator coil where it exchanges heat with a refrigerant, prior to being blown across the battery assembly. The cooling air may be recirculated across the battery assembly, or exhausted from the vehicle through an air extractor.

  • Publication number: 20090155680
    Abstract: A power supply system includes a number of battery cells connected in rows in an end-to-end fashion to form a battery module. A number of these battery modules are placed into a housing to form a battery brick, which is a basic building block that can be used to create a larger battery assembly. The power supply system may include locators to position individual battery cells within a row, to help ensure proper alignment of battery terminals extending outside the battery housing. Terminal connectors can be used to reduce the magnitude of the voltage seen across exposed terminals. The terminal connectors connect two of the battery terminals, while covering, and inhibiting access to, adjacent battery terminals. The power supply system may also include sensor stations to facilitate use of temperature sensors such that uniformity of airflow around the battery cells is maintained regardless of how many temperature sensors are used.

  • Patent number: 7234552
    Abstract: A method for heating a battery in a hybrid electric vehicle. The hybrid electric vehicle has an engine, a battery, a motor generator powered by the engine or the battery, and a control module. The method includes the steps of determining a battery temperature and determining whether a tip-in event, a tip-out event, or a terminal voltage event has occurred. The polarity of the battery is reversed if the battery temperature is below a predetermined value and if a tip-in event, a tip-out event, or a terminal voltage event has occurred.
