    Abstract: Circuits, methods, and apparatus that provide for the powering of active components in connector inserts at each end of a cable may in various ways. For example, where a host is coupled to a device that is not self-powered, the host may provide power for circuitry at each end of the cable. In various embodiments of the present invention, the device may request higher voltage from the host, such that more power can be delivered. In these cases, the device may regulate the voltage received from the host to a lower voltage, and then provide the lower voltage to circuitry at one or both ends of the cable. Where the host is connected to a device that is self-powered, the host and the self-powered device may power their respective connector insert circuits.

    Abstract translation: 可以以各种方式提供在电缆的每个端部处的连接器插入件中的有源部件的供电的电路,方法和装置。 例如,在主机耦合到不是自供电的设备的情况下,主机可以在电缆的每一端为电路提供电力。 在本发明的各种实施例中,设备可以请求来自主机的较高电压,使得可以传送更多的功率。 在这些情况下,该装置可以将从主机接收的电压调节到较低的电压,然后向电缆的一端或两端的电路提供较低的电压。 在主机连接到自供电设备的地方,主机和自供电设备可以为其各自的连接器插入电路供电。

    Abstract: Various techniques related to authenticating and verifying the integrity of data received by a computer system from an external source (such as a sensor) are disclosed. Hardware circuits are disclosed that, along with the computer processor, allow for error-checking and authentication of data received by the computer system. For instance, the hardware circuits may generate a separate authentication code that can be compared to the authentication code in the data itself to determine whether or not the message is authentic and whether or not there is an error in the data. The disclosed techniques reduce the processing requirements of a computer system and can be implemented using simple hardware circuit designs.

    Abstract: Systems for power over data line applications with low mode conversion are described. For example, an apparatus may include a magnetic core; a first conductive coil wound in a first winding direction around the magnetic core; a second conductive coil wound in a second winding direction around the magnetic core; a first conductive lead connecting a first end of the first conductive coil to a first pin; a second conductive lead connecting a second end of the first conductive coil to a second pin; a third conductive lead connecting a first end of the second conductive coil to a third pin, wherein lengths of the first conductive lead and the third conductive lead are equal; and a fourth conductive lead connecting a second end of the second conductive coil to a fourth pin, wherein lengths of the second conductive lead and the fourth conductive lead are equal.
