Abstract: Described herein are embodiments for managing policies of a mobile device. In embodiments, a mobile device receives policy containers from a plurality of disparate management agents. Each policy container has one or more policies. Each policy corresponds to a particular category that governs various aspects of the device. The policies described herein may be device wide policies corresponding to various features on the device. The policies may also be data specific policies which dictate how data is stored on and transferred to and from the device. Once the policies are received, a determination is made as to which policy in each category is the most secure policy. The most secure policy for each category is merged to create a global policy that is applied to the mobile device.

Abstract: An electronic device may be configured to identify a load coupled to the device. The device may measure direct current (DC) and/or alternating current (AC) characteristics of the load to identify the load. The device may then take action based on the identification of the load. For example, a specific transducer may be identified as coupled to the electronic device and an appropriate equalization curve applied to an audio output of the device. The measurement of characteristics of the load may include controlling a reference generator according to a search algorithm, such as a step ramp or binary search, to identify the load. An analog-to-digital converter (ADC) may operate through the search algorithm to provide feedback to digital circuitry regarding how to proceed through the search algorithm to identify the load.

Abstract: A cylindrical receiver has an upper region with female screw threads, a lower region, and a centrally located washer. A cylindrical sleeve has an upper end with male screw threads threadedly coupled to the female screw threads of the receiver. A cylindrical passageway is formed between the receiver and the sleeve. A cylindrical stake is slidably received in the sleeve. A tether line couples the stake to a movable patch whereby when the movable patch is coupled to a fixed patch, the stake will be in a raised orientation and whereby when a user separates the movable patch from the fixed patch, the weight of the stake will lower the stake into a lower orientation into a sandy or rocky bottom.

Abstract: A medical product comprises a biodegradable filament and a non-biodegradeable coating. The biodegradable filament forms a stent body having a first end portion, a middle portion, and a second end portion opposite the first end portion. The middle portion extends between the first and second end portions. The non-biodegradeable coating encapsulates the at least one biodegradable filament along the middle portion of the stent body. The non-biodegradeable coating forms a barrier such that the non-biodegradeable coating prevents degradation of the at least one biodegradable filament along the middle portion. The first and second end portions are uncoated. After implantation, the end portions of the stent may biodegrade. The middle portion will not biodegrade due to its encapsulation by the non-biodegradeable coating.

Abstract: A portable audio device may be configured to measure load characteristics of headphones. The device may measure direct current (DC) and/or alternating current (AC) characteristics of the load. These characteristics may be measured by an audio component, such as an audio codec chip or integrated circuit (IC) controller, and reported to software or firmware executing on a processor coupled to the audio component. The software or firmware may then take action based on the measured load characteristics. For example, the load characteristics may be compared to a database of headphones and their known load characteristics to determine a particular headphone model or type of headphone attached to the audio output. The processor may then apply an appropriate equalization curve.

Abstract: An energy-efficient consumer device audio power output stage with gain control provides improved battery life and reduced power dissipation without clipping the audio output signal. A control circuit controls a power supply that supplies the power supply rails to the power amplified output stage. The voltage of the power supply rails is controlled in conformity with an input audio signal level, which may be determined from a volume control setting of the device and/or from a signal level detector that determines the amplitude of the signal being amplified. The gain applied to the audio input signal is reduced for a predetermined time period when a higher output voltage of the power supply is selected, to avoid clipping the audio output signal.
