Abstract: A physical container (e.g., a battery) may be filled up (charged) or emptied (discharged) with energy commensurate with requirements to post a particular amount of collateral. The disclosure provides computing systems and methods for processing data using a novel combination of wavelet techniques and rolling techniques to more efficiently detect seasonality in particular products (e.g., energy products) to more accurately model and determine collateral/margin requirements. A clearinghouse computing device may be configured to generate a margin requirement for a portfolio of products and may include a processor to process instructions that cause the clearinghouse computing device to perform wavelet decomposition and rolling methods on a historical database of records.

Abstract: A radio frequency signal coupler includes an input port, an output port, a main transmission line coupled between the input port and the output port, and a coupled transmission line electromagnetically coupled to the main transmission line. The coupled transmission line includes a first transmission line, a second transmission line, and a switch configured to couple the first and second transmission lines during a first mode of operation and to decouple the first and second transmission lines during a second mode of operation. The radio frequency couple can be used in a front end module of a communications device, such as a mobile phone.

Abstract: According to some aspects of this disclosure a radio frequency signal coupler is provided. The radio frequency coupler includes an input port, an output port, a main transmission line extending between the input port and the output port, a coupled transmission line electromagnetically coupled to the main transmission line, at least one coupled port coupled to the coupled transmission line, and a plurality of termination ports connected to the coupled transmission line, each termination port of the plurality of termination ports being connected to the coupled transmission line at a different location to provide a plurality of coupling factors corresponding to a plurality of signal frequencies.

Abstract: An amplifier system for radio frequency hot switching of a power amplifier can include a field-effect transistor, a forward biasing network, and a reverse biasing network. The forward biasing network is configured to provide a positive bias voltage to a gate terminal of the field-effect transistor, and the reverse biasing network is configured to provide a negative bias voltage to the gate terminal, with resistance of both biasing networks selected to independently control an on and off-switching time of the field-effect transistor. The independent on and off-switching time can allow for rapid “hot switching” in a connected power amplifier while the power amplifier is energized, while reducing spurious emissions of radio frequency signals by the power amplifier.

Abstract: A system may be configured to generate an estimate of value at risk and may include a processor to process instructions that cause the system to generate a rolling time series of value data having a plurality of dimensions, perform a transformation of the time series, perform variance scaling and correlation scaling on transformed time series, reverse transform the results of the scaling, and estimate of a value-at-risk for the value data.

Abstract: A method of attaching a zipper (42) to a carrying case (40) to define an interior compartment or pocket (60). Opposed edges (52, 54) of a single piece of material (50) are folded under and are sewn to respective top (62) and bottom (64) surfaces of a tape (48) of the zipper to form a double layer of the material (58) extending from the zipper. A fold line (56) is formed in the double layer of material, and the fold line is sewn to the body (44) of the case. Stitching steps are minimized, no raw edge is exposed to the interior volume, and the double layer of material provides strength.

Abstract: A radio-frequency module has radio-frequency input and outputs and a radio-frequency core connected between them and configured to transition between operational states.

Abstract: A storage rack apparatus including a locking mechanism that secures a bracket (10) to a supporting member such as a wall-mounted rail (48) or panel (54). A securing bar (36) is rotatably attached to the body (12) of the bracket and is rotatable between unlocked (FIGS. 3 and 6) and locked (FIGS. 4, 5, 7, and 8) positions. In the unlocked position, an unlocking portion (44) of the securing bar does not make contact with the rail or panel. In the locked position, a locking portion (46) of the securing bar makes forced contact with a front surface (50, 62) of the supporting member, thereby placing the hooks (24, 26) of the bracket into frictional engagement with the rear surface (16) of the supporting member to resist movement of the bracket from its installed position.
