Abstract: A stack of eye shields includes a plurality of eye shields each having a frame with receivers located along the frame and latches located to engage the receivers, and spaced apart elevated support surfaces along and rising above an upper portion of the frame; and a lens installed on the frame and having lens apertures extending through the lens and aligned with the receivers of the frame, with the latches engaged with the receivers securing the lens to the frame. The eye shields are stacked one on top of another with each of the eye shields oriented substantially parallel to one another with each of the elevated surfaces of an overlying one of the frames of the stack being slightly forward of a corresponding one of the elevated surfaces of the underlying frame of the stack, with each frame of each eye shield of the stack having a gap therebetween except at contact surfaces where the elevated support surfaces contact an adjacent lower surface of an overlying eye shield.

Abstract: Light-emitting devices including solid-state light-emitting devices, light-emitting diode (LED) devices, and LED packages with support elements for improved near-field and far-field emissions are disclosed. LED chips may be mounted to support elements in a manner that directs light through the support elements in desired emission directions. Support elements include optical structures that spread and mix light laterally within the support element. Optical structures include interior mixing chambers bounded by light-altering layers, such as light-diffusing layers or light-reflective layers, that effectively increase internal reflections within the mixing chambers for lateral spreading of light. Support elements as described may be well suited for low profile LED devices where device heights are less than or equal to device widths.

Abstract: A rotary tool for operation within an underground borehole or within tubing in a borehole has a tool body and at least one sensor-containing unit attached to the tool body and positioned to contact the conduit wall. The sensor-containing unit includes an exterior portion to contact the borehole or tubing wall and one or more sensors is located in a cavity between the exterior portion and the tool body. The sensor-containing unit may be formed from the exterior portion, an attachment portion for attachment to the tool body, and one or more connecting portions extending between the attachment and exterior portions, with the sensor-containing cavity between the attachment and exterior portions. Possible rotary tools include drill bits, reamers, mills, stabilizers, and rotary steerable systems.

Abstract: A rotary tool for operation within an underground wellbore or within tubing in a wellbore has at least one force-sensitive element attached to the tool body and positioned to contact the conduit wall, wherein the force-sensitive element comprises an outer portion to contact the wellbore or tubing wall, at least one connecting portion which is more compliant than the outer portion and through which the outer portion is connected to the tool body, and at least one sensor responsive to force on the outer portion transmitted through the force-sensitive element to the tool body. The sensors may resolve forces into measurable forces on three axes. Possible rotary tools include drill bit, reamer, mill, stabilizer and rotary steerable system for a drill bit.

Abstract: This massage device is configured to apply pressure to a human user's back, shoulders, or any distinct part of the musculoskeletal system. It can also be operated with a single arm and attaches to the user's forearm to apply pin-point or various pressure to target muscles. The massage device includes an arm plate that is configured to cover a forearm and a wrist of a human user. A hand grip is mechanically coupled to the arm plate and configured to accommodate the gripping of human fingers. A wrist bar is attached to the arm plate. A J-bar may be attached to the wrist bar. A tip is attached to the J-bar or directly to the short wrist bar. The tip is configured to provide variant pressure to the human user's back or shoulders or distal body part. Thereby duplicating mechanical pressure applied by a trained bodyworker by the untrained self at a much more reasonable price.

Abstract: An inflatable ride-on water toy comprising a stylized body that is connected to a separately inflated safety ring using a variety of configurations.

Abstract: A data center supporting a network system for vending products to customers and associated vending methods are provided. The network system includes a data center and a plurality of vending stores remotely located from the data center and connected to the data center through a network interface. The vending stores also include an automated dispensing mechanism for immediate dispensing of purchased products to the customers. The data center may include an enterprise resource planning module and the vending stores may contain user interfaces for collecting inventory and maintenance data during stocking and maintenance.

Abstract: A method for detecting an influx and/or loss of circulation in a wellbore, comprising measuring a condition in the wellbore using a downhole sensor; determining that a positive displacement pump is shut off or turned on; predicting pit volume and/or gas concentration at a plurality of time points after the positive displacement pump is shut off or turned on using the measured condition in the wellbore prior to the positive displacement pump is shut off or turned on, wherein the measured condition correlates with the pit volume and/or gas concentration; measuring pit volume and/or gas concentration at the plurality of time points; comparing the predicted and the measured pit volumes and/or gas concentrations at the plurality of time points; and producing a warning signal if the difference between the predicted and the measured pit volumes and/or gas concentrations is greater than a pre determined value.
