Abstract: A sports bra exhibits increased resistance in response to increased force. The sports bra includes a front curved region for accommodating a wearer's breasts, the front curved region including a shear-thickening foam. The shear-thickening foam is relatively flexible up to a first force and is relatively rigid above the first force to retain the wearer's breasts within the front curved region during vigorous physical activity. A back panel connecting to the front curved region such that the force is at least partially transferred to an upper back or shoulder region of the wearer. A body protecting element protects a body part from an external impact, the body part selected from head, knee, shin, elbow, foot, leg, torso, arm, wrist or hand. The body protecting element includes a housing conforming to the shape of the selected body part. A shear-thickening foam is included in the housing.

Abstract: Embodiments of the present disclosure provide an activation method, an activation device, a control device, a network device and an optical network system. A new-system ONU is activated on a first OLT in an existing system, and then activation information of the new-system ONU is sent to a second OLT in a new system by the first OLT or by an activation agent ONU which has been activated on the second OLT, thereby enabling activation of the new-system ONU on the second OLT.

Abstract: A ventilation structure of a core chamber of a turbofan engine having a large bypass ratio, said structure comprising: an outer bypass wall surface (1), a core chamber wall surface (4) and a core casing (7). An outer bypass flow channel (2) is formed between the outer bypass wall surface (1) and the core chamber wall surface (4). A core chamber (6) is formed between the core chamber wall surface (4) and the core casing (7). An air intake annular cavity (3) is provided in the core casing and is located at the upstream position. The air intake annular cavity (3) is used to put the outer bypass flow channel (2) and the core chamber (6) in communication. An exhaust grille (5) is further provided on the core chamber wall surface (4) and is located at a tail position.

Abstract: An exemplary illuminator includes a first electrode, a second electrode, and a light-emitting chip. The light-emitting chip includes light-emitting layers arranged three-dimensionally. The first and second electrodes are configured for providing different voltages to the light-emitting chip, and the light-emitting chip is capable of emitting light simultaneously along all dimensional axes.

Abstract: A high speed optoelectronic subassembly in an optoelectronic package is disclosed that includes a dielectric support having a first electrical trace on a surface thereof and a dielectric member mounted on the surface of the support having a second electrical trace thereon. The support extends laterally a distance greater than the member to form a shelf. A dielectric step is positioned on the shelf abutting an end of the member and a laser is positioned on the shelf adjacent the step so as to be light accessible external to the subassembly. The laser and the step have surfaces equal in height and cooperate to provide a mounting platform. A resistive element is positioned on the mounting platform and electrically connected to the laser, the resistive element and laser being electrically externally accessible through the traces.

Abstract: A laser transmitter with a laser diode and first and second feedback loops for maintaining a constant average laser power output and constant extinction level. A photo detector samples and detects transmitter laser light. The detector output is split, with one portion sent to a low-pass detector circuit for detecting the average laser power and using the detected signal to control a laser power current bias source. The other portion of the detector output is delivered to a high-pass detector circuit for detecting the amplitude of the modulation for outputting a signal to control a modulation laser current source that adds to the power current bias for a logic “1” state and does not add to the power bias for a logic “0” state.
