    • A collapsible flotation device is provided that uses a coilable spring coupled to a panel to collapse the device when the spring is coiled, and to expand the device when the spring is uncoiled configuration. The spring can be contained within a sleeve along the outer portion of the panel. A support member that traverses the panel is provided. An inflatable bladder disposed about a part of the outer portion of the panel and coupled to the support member buoyantly supports a body weight of a user. The combination of the inflatable bladder and the support member provide support for a user in a seated position on the panel. Many configurations are disclosed, including a multi-user collapsible flotation device, multiple connected single-user flotation devices, and so forth. A back support member and a headrest, both of which can be inflatable, provide additional support for a user to maintain a seated position on the panel. A foot support member is provided for the comfort of the user.

    • An improved carrier release sheet is described for use with biopotential skin electrodes of the type including a stud, a pad preloaded with an electrically conductive material and in electrical contact with the stud, a base sheet having an aperture and secured to said stud so that the pad is exposed through the aperture to one side of the base sheet having an adhesive coating. The carrier release sheet includes a cylindrical cavity of an improved configuration for receiving the preloaded pad of the electrode in a noncontacting relationship and a tab integrally formed with the remainder of the carrier release sheet so as to enable quick and easy release of the carrier sheet from the adhesive coating.

    • The present invention provides methods and apparatus for calibrating and controlling output power levels in a broadband communication system. The power level of an intermediate frequency (IF) signal may be varied at a first attenuator. The IF signal from the first attenuator may be frequency converted at a mixer to provide a desired transmit frequency converted signal. The power level of the frequency converted signal may be adjusted at a second attenuator. The signal may be sampled after the second attenuator in order to detect its output power level. The detected output power level may be compared with a reference level to obtain a difference signal. The difference signal may be used in a feedback loop to adjust the power level of the signal output from the first attenuator so that a constant output power level is maintained. Methods and apparatus for calibrating output power levels are also provided.
    • 本发明提供了用于在宽带通信系统中校准和控制输出功率电平的方法和装置。 中频(IF)信号的功率电平可以在第一衰减器处改变。 来自第一衰减器的IF信号可以在混频器处进行频率转换以提供期望的发射频率转换信号。 可以在第二衰减器处调整频率转换信号的功率电平。 可以在第二衰减器之后对信号进行采样,以便检测其输出功率电平。 可以将检测到的输出功率电平与参考电平进行比较以获得差分信号。 差分信号可以用在反馈回路中以调整从第一衰减器输出的信号的功率电平,使得保持恒定的输出功率电平。 还提供了用于校准输出功率电平的方法和装置。
