Abstract: In one embodiment, a method includes accessing a window of motion data collected by a motion sensor of a device worn by a user and selecting motion data in the window about or more particular axes of the motion sensor. The method further includes determining a ballistocardiogram (BCG) signal in the selected motion data and determining whether the BCG signal in the selected motion data satisfies a signal-quality metric. If the BCG signal in the selected motion data satisfies the signal-quality metric, then the method includes (1) determining one or more heart-beat metrics of the user from the selected motion data; and (2) estimating, based on the one or more determined heart-beat metrics, a stress condition of the user at a time coincident with the window of motion data.

Abstract: A process is described herein for producing a low-volatile-matter organosilicon linear body. The process can include: removing chlorine ions from a dimethyl dichlorosilane hydrolysate, and reducing volatile matters at 180-280° C. and ?0.0955 to ?0.0998 MPa. The obtained organosilicon linear body can have volatile matters of less than 0.5%, a viscosity of 50-150 mm2/s and a content of chloride ions of lower than 1 ppm. The process can be widely applied to the production of organosilicon subsequent products such as low-ring-body-content 107 glue, low-ring-body-content amino silicone oil, low-ring-body-content methyl silicone oil, and low-ring-body-content vinyl silicone oil, and can meet requirements of the European Union on content limitations of ring bodies in a polymer.

Abstract: A press-in fastener has from top to bottom: a head, a clinch feature, and a spiral, knurled shank. The fastener can hold two parts together by first clinching with a first metal panel, and then being pressed into a hole in a second, less ductile panel having a uniform interference between the knurled fastener shank and the hole. The knurled shank has a helix configuration that allows for use in non-ductile materials and eliminates the need for tapered holes and screws for applications that do not require disassembly.

Abstract: A recording head comprises a write element, including a coil and a dynamic fly-height heater, and two electrical lapping guides. The head also comprises a number of bonding pads including a DFH bonding pad and a shared bonding pad both electrically connected to the dynamic fly-height heater. Each lapping guide defines a circuit between the shared bonding pad and a dedicated bonding pad and each includes a resistive element. The resistive elements of the two lapping guides can be vertically aligned to be used to control a lapping tilt angle when a bar of unfinished heads is lapped. After lapping, a channel is defined into the transducer of the recording head. Forming the channel can remove at least a portion of each lapping guide in order to break the electrical circuit of that guide.
