摘要:
Systems and methods for managing media playback are described. In one embodiment, a third party media request is received from a third party application. A native media request is sent to a native media player in response to the third party media request. The native media request causes the native media player to access content or metadata. Metadata is returned to the third party application if the third party media request requested data. The native media player performs a content operation on the content if the third party media request requested a content operation.

Disclosed are thionated fused-ring (aromatic) imides and diimides that can exhibit desirable electronic properties and can possess processing advantages including solution-processability and/or good stability at ambient conditions.
摘要:
Disclosed are polymer-based dielectric compositions (e.g., formulations) and materials (e.g. films) and associated devices. The polymers generally include photocrosslinkable pendant groups; for example, the polymers can include one or more coumarin-containing pendant groups.

An encapsulated transformer includes a transformer coil assembly, a rigid core insert having an upstanding portion positioned within the hollow interior of the core and a base portion on which the core rests, and a thermoplastic rubber jacket that completely surrounds the transformer coil assembly and is bonded to the base portion of the core insert to provide a completely waterproof encapsulated transformer which is impervious to liquid and gasses that could be detrimental to the performance of the transformer. A method for producing such an encapsulated transformer includes placing a rigid core insert in a mold cavity of a mold, and positioning a transformer coil assembly in the mold cavity so that the transformer coil assembly rests on the core insert. Thermoplastic rubber is then injected into the mold cavity to completely encapsulate the transformer coil assembly in a jacket of thermoplastic rubber. During the injection step, gas in the mold cavity is vented through a vent space provided in the bottom surface of the mold cavity. A mold for encapsulating a transformer coil assembly in thermoplastic rubber includes a bottom mold portion having a mold cavity, an upstanding pin disposed within the mold cavity, a mold cover for closing the mold cavity, and a vent space positioned in the bottom surface of the mold cavity for venting gas within the mold cavity to the exterior of the mold during the injection of thermoplastic rubber into the mold cavity.

A mass spectrometer having a mass filter which applies a transient voltage profile to accelerate ion packets. The voltage profile is chosen to have a functional form which imparts each ion species with a kinetic energy which is larger the larger the mass-to-charge ratio and a velocity which is smaller the larger the mass-to-charge ratio. The ions are detected in an ion detector which discriminates between different ion species based on their kinetic energy and taking account of the functional form of the voltage profile. Suitable voltage profiles include periodic functions such as sinusoids, triangles and sawtooths, which allow the amplification of drive pulses in the mass filter to be carried out with narrow band amplification stages, which are simple and inexpensive to construct.

The present invention discloses the use of PSP-94, PCK3145 and other derivatives and biologically active analogues for treating a patient having a condition such as metastasis, metastatic cancer, a condition associated with elevated levels of parathyroid hormone-related protein (PTHrP), PTHrP-induced osteolysis and/or hypercalcemia of malignancy. These compounds were found to be effective treatment modalities for bone metastasis caused by prostate cancer. Furthermore, decrease in cellular and plasma PTHrP levels as well as plasma calcium levels observed by treatment with such compound can serve as useful biochemical markers for monitoring the efficacy of these anti-metastatic compounds.
