Abstract: Techniques for identifying a trusted SSID for a wireless network are disclosed. Prior to establishing a connection with a wireless network, a first network message is received from a first access point (AP) identifying a first service set identifier (SSID) associated with a first wireless network, a second network message is received from a second AP identifying a second SSID associated with a second wireless network, and a visual similarity is determined between a first visual representation of the first SSID and a second visual representation of the second SSID. The second SSID is designated as suspicious based on the determined visual similarity.

Abstract: A method of operating a compressor of a compressor system uses three models. Each model of the three models describes a surge line of the compressor as a function of any two of three operating parameters of the compressor. The three operating parameters include head (H), flow (Q), and speed (N). The method includes measuring operating characteristics of the compressor system using sensors, and determining a current value of the three operating parameters based on at least some of the measured operating characteristics. The method also includes locating operating points of the compressor on each of the three models based on the current value of the operating parameters, and identifying a sensor fault that affects the determination of at least one of the operating parameters. The method further includes avoiding surge of the compressor using one model of the three models. The one model being a model that is a function of two operating parameters unaffected by the sensor fault.

Abstract: A card edge connector is provided with a housing and electrical contacts. The housing has a card edge receiving area, end supports located at opposite ends of the card edge receiving area, and stability outriggers. The end supports extend up from a top surface of the housing and each has a slot for receiving a portion of a printed circuit board. The outriggers extend outward from lateral sides of the housing at the bottom of the housing. The outriggers also function as standoffs for the housing.

Abstract: A card edge connector with a housing and electrical contacts. The electrical contacts are spaced from adjacent contacts at a center-to-center pitch of 0.025 inch. The contacts each have a middle section that is interference fit in a contact receiving channel of the housing. The middle sections each have a general ring shape with a center electromagnetic reduction aperture. The ring shape forms a structural truss to retain structural rigidity of the middle section to enable the interference fit to be made and, the center electromagnetic reduction aperture reduces capacitance between the closely spaced adjacent contacts.
