Abstract: An integrated local sports league tracking and scoring system includes a local sports management server. The server includes a league management component executable on the local sports management server, the league management component managing payment, scheduling, and team registration operations for one or more local sports leagues. The server further includes a player management component executable on the local sports management server, the player management component managing a plurality of players associated with the one or more local sports leagues. The server includes a scoring component executable at least in part on the local sports management server, the scoring component configured to receive realtime data regarding scoring of a game occurring in the one or more local sports leagues, the scoring component including a user interface displayable on a remote system.

Abstract: A wideband low noise RF amplifier (LNA) (100) comprising an inductorless internal amplifier load (102). The load can include a first resistor (104) coupled to an external load or a load isolation stage (150) and a first current source (112) connected in parallel to the first resistor to provide at least a first portion of load current. The load also can include a second resistor (106) coupled to the external load or the load isolation stage and a second current source (114) connected in parallel to the second resistor to provide at least a second portion of load current. The first and second current sources can include metal oxide semiconductor field effect transistors (MOSFETs). A biasing system (136) can be provided to bias the first and second MOSFETs.

Abstract: A tray connects with various high chairs and securely attaches various food receptacles to resist knocking over by a small child or toddler seated within the high chair. The tray has an annular slot with curved wider and curved narrower slots in alternating sequence. A complementary curved channel, located beneath each slot, communicates with each cooperating narrower slot and adjacent wider slots. Food receptacles, such as bowls, plates, and the like are releasably attached to the tray over the annular slot. Each food receptacle contains curved anchor members located on the bottom in a circular pattern complementary to the annular slot. The infirm and the elderly may also benefit from this tray.

Abstract: A receiver (202) has a down-conversion receiver (304) for transforming a signal (201) from a first operating frequency to a second operating frequency that is lower than the first operating frequency, and a receiver filter (308) with chopper stabilization for filtering unwanted portions of the signal (306) at the second operating frequency and for generating a final filtered signal (203) at the second operating frequency.

Abstract: A mixer circuit (50) includes a first switching mixer (20A) with a first desired signal input (RF+ and RF?), a first switching signal input (LO+& LO?), and a first output (IF+ and IF?), a second switching mixer (20B), and a third switching mixer (20C) with corresponding desired signal inputs, switching signal inputs, and outputs. An overall input signal to the mixer circuit is fed to an input port (56) of the first switching mixer, an output from an output port (57) of the first switching mixer is fed to an input port (58) of the second switching mixer, the output from an output port (59) of the second switching mixer is fed to an input port (60) of the third switching mixer, and an overall output of the mixer circuit can be an output from an output port (62) of the third switching mixer.

Abstract: The present invention has tray that connects with various high chairs and securely attaches various food receptacles so that the receptacles resist knocking over by a small child or toddler seated within the high chair. The tray has an annular slot with curved wider and curved narrower slots in alternating sequence. A complementary curved channel, located beneath each slot, communicates with each cooperating narrower slot and adjacent wider slots. Food receptacles, such as bowls, plates, and the like are releasably attached to the tray over the annular slot. Each food receptacle contains curved anchor members located on the bottom. The anchor members have a circular pattern complementary to the annular slot. A food receptacle attaches to the tray by inserting the anchor members of the food receptacle into the wider slots and rotating the food receptacle clockwise.
