  • Patent number: 9427349
    Abstract: The present invention provides an athletic brace which is composed of a flexible sleeve and a rigid framed brace. An elastic tubular shaped fabric sleeve is first placed over the elbow or knee joint and has upper front and lower rear raised lips that are used to prevent the rigid and compact framed brace from slipping downwards during usage. The tight fit of the rigid brace inside the raised lip gaps of the sleeve prevents the framed brace from slipping down from the elbow or knee joint during usage. This brace is designed to also be compact in size to allow for everyday wear in both contact and non-contact sports for both elbow and knee protection.

  • Publication number: 20160123342
    Abstract: Systems and methods to clamp an impeller on a shaft in a centrifugal compressor. The embodiments as disclosed herein may include clamping individual impeller independently to the shaft, which may reduce the tolerance stack-up effect of a plurality of impellers. The impeller can be clamped to the shaft by positioning, for example, a relatively stiff support (e.g. a shaft locknut) on a front side of the impeller. The impeller can also be clamped to the shaft by a relatively flexible support to compensate for e.g. thermal expansion/contraction of the impeller. The embodiments as disclosed herein are particularly suitable for a multi-stage impeller.

  • Publication number: 20160123347
    Abstract: An actuation linkage assembly may include a first lever arm connected to one end of a shaft, a second lever arm connected at one end to another end of the shaft, a transition linkage connected to the other end of the second lever arm, and a bracket connected to the transition linkage. The transition linkage is configured to connect the bracket on a driver ring and to the shaft to transfer rotational motion about the axis of the shaft, from a linear motion received by an actuator, to a linear motion through the bracket causing rotational motion of the driver ring. The actuation linkage assembly is configured with high mechanical advantage. The actuation linkage assembly can be part of a movable inter-stage vane guide assembly in a compressor such as for example a centrifugal compressor, which may be part of a chiller such as in a HVAC system.

  • Patent number: 9313198
    Abstract: Systems and methods of authenticating users using a possession factor communicate a first authentication code to the user device and a second authentication code to an authentication device that is assumed to be the user's possession. Both authentication codes are presented to the user via their respective devices. An authentication application on the authentication device asks the user to compare the authentication codes and respond, via the authentication device, if these two authentication codes match. Authentication codes may be identical or different and match based on a user association. If a message from the authentication device indicates that the two codes match, then it is confirmed that the user possesses the authentication device and has authorized the authentication to proceed. For enhanced security, the authentication application may optionally be installed and executed on a Subscriber Identity Module (SIM) installed in the authentication device.

  • Publication number: 20160015067
    Abstract: The present invention is directed to natural blue anthocyanin-containing colorants comprising fractions of anthocyanin molecules separated from anthocyanin-containing vegetable and fruit juices and extracts. Anthocyanin fractions are separated at a select pH based on differences in polarity of the anthocyanin molecules in the anthocyanin-containing vegetable and fruit juices and extracts. The invention is directed to the anthocyanin fractions providing color characteristics similar to those provided by the synthetic blue colorant, FD&C Blue No. 1. The present invention is also directed to natural green colorants comprising the natural blue anthocyanin-containing colorant and a natural yellow colorant. The present invention is further directed to edible products comprising the natural blue anthocyanin-containing colorants.

  • Publication number: 20150248618
    Abstract: In accordance with an embodiment, described herein is a system and method for logistic matrix factorization of implicit feedback data, with application to media environments or streaming services. While users interact with an environment or service, for example a music streaming service, usage data reflecting implicit feedback can be collected in an observation matrix. A logistic function can be used to determine latent factors that indicate whether particular users are likely to prefer particular items. Exemplary use cases include providing personalized recommendations, such as personalized music recommendations, or generating playlists of popular artists.
