Abstract: Disclosed herein is an apparatus for facilitating improving flow of fluid in a duct, in accordance with some embodiments. The apparatus comprises a first portion, a third portion, and a second portion. Further, continuously attaching an inlet edge using an attachment member and an outlet edge defines an interior space. Further, a first amount of the fluid entering a first interior space through an inlet opening flows to a third interior space with a first velocity and a first direction. Further, portions of a second amount of the fluid flows into the third interior space through second openings with a second velocity and second directions. Further, the fluid flows from the third interior space with a third velocity and a cyclonic flow pattern for exiting through an outlet opening based on interacting of the portions of the second amount of the fluid with the first amount of the fluid.

Abstract: A bladeless cooling light includes an airflow assembly, a light assembly, and a housing. The airflow assembly includes an air circulation assembly positioned within the housing and an air passage structure connected to the housing, wherein the air circulation assembly draws air through the housing into the air passage structure. The air passage structure has a separation wall that delineates the air passage structure into an inflow air channel and an outflow air channel to improve the airflow through the air passage structure. A cone-tip hole grid and a wired heater within the air passage structure further improve airflow characteristics; the cone-tip hole grid constricts the flow, while the wired heater increases internal pressure by heating the air. The lighting assembly is mounted to the housing with the air passage structure being positioned around the lighting assembly, such that the light and expelled airflow are projected in the same direction.

Abstract: The present disclosure relates to semiconductor devices and discloses a method for operating a flash memory. When a read operation is performed on a flash memory unit, a potential of a first control line connected to gates of select gate PMOS transistors located in a same row is switched from a positive supply voltage to 0V. Since it is not required to switch the potential from a positive voltage to a negative voltage, the power consumption of the pump circuit is significantly reduced. In addition, a read current of the flash memory unit selected for reading can accurately represent the status of the unit being read thanks to the appropriate settings of the gate oxide layer thickness and the threshold voltage of the select gate PMOS transistor. Furthermore, high-voltage devices are removed from the read path and only low-voltage devices are used, so that the reading speed can be significantly improved during the read operation.

Abstract: Devices in a network environment may have a local client application that may periodically update software components on a local device and may configure user access and other parameters to the software component for individual users. The client application may operate by querying a domain server and may receive a description of available software components. After identifying a component to install, the client application may download the component from a data store and install the component, then configure individual user access to the component.

Abstract: Described is a technology by which machines of a (typically small) network have associated public key-based certificates for use in authentication with a server and validation of other machines in the network. This provides an inexpensive and straightforward mechanism to control, manage and maintain client machines, as well as to allow valid client machines to securely communicate with one another and recognize machines that are not valid on the network. Certificates are maintained on the server and checked for validity as needed.

Abstract: A driver circuit integrated light emitting diode (LED) module is a device that is designed for installation into a conventional lighting fixture and as a replacement for a conventional lighting device such as an incandescent lightbulb. The device features a printed circuit board (PCB) onto which a plurality of LEDs is mounted for illumination. Incoming alternating current (AC) power is converted to usable direct current (DC) power by a rectifier prior to entering the PCB. A control module is used to regulate the current through the plurality of LEDs, allowing the device to be utilized in conjunction with a dimmer switch or similar device. The device is connected to mains electricity and/or to an external electronic device via an at least one electrical connector cable. Flickering is prevented by a uniform power regulating capacitor. The device is installed into an existing lighting fixture via an at least one mounting magnet.

Abstract: An authentication mechanism in a local area network may use a cloud authentication mechanism to allow or deny authentication requests. A user may gain access within a local area network by entering a cloud identification and password, which may be verified by a cloud authentication mechanism. If the authentication is successful from the cloud authentication mechanism, the user identification and password are stored locally for subsequent authentication requests. In some embodiments, the cloud password may be periodically flushed so that subsequent requests may be passed to the cloud authentication mechanism. The authentication mechanism may be used in both domain and workgroup local area networks, and may operate in parallel with other users who may have local area network or client credentials which may not be authenticated from the cloud.

Abstract: The subject disclosure is directed towards establishing communication between a client computer and a network resource on a computer network when DNS resolution has failed because of a DNS proxy solution. A user may request that the client use a tool as an alternative to DNS resolution. The client may monitor the network for a broadcast from the network resource, which contains information needed for the client to access the network resource. The network resource may broadcast the information from time to time, or it may broadcast it in response to a specific request from the client.
