Embodiments provide WiFi and LTE tailored transceiver radio frequency (RF) filtering techniques and configurations to enable coexistence between WiFi and LTE transceivers operating in close proximity. In particular, embodiments provide filtering techniques to reject emissions from LTE into WiFi, and vice versa. The filtering techniques eliminate the need for additional isolation between LTE and WiFi antennas (approximately 50 dB), which is beyond what is achievable in practice. Embodiments can be tailored according to different use cases of the WiFi and LTE transceivers (e.g., fixed CPE, portable router, smart phone with tethering).

Wireless transceivers with filter arrangement for WiFi and LTE coexistence

Various embodiments of the present invention recognize at least two zones of operation for a communication device. In a first zone, which is sufficiently spaced away from a human head or body that SAR limits will be met, transmit power delivered to an antenna of a communication device may be maximized within any other constraints under which the communication device operates. In a second zone, which is not sufficiently spaced away from a human head or body, transmit power is redistributed such that SAR limitations are met without affecting the transmit power control loop of the communication device. For example, a second antenna physically disposed at a different location within the communication device may be used either instead of, or in addition to, the first transmit antenna in order that the SAR limits are met.

Distribution of transmit signal to multiple transmit antennas for reduction of measured specific absorption rate

Embodiments provide WiFi and WiMAX tailored transceiver radio frequency (RF) filtering techniques and configurations to enable coexistence between WiFi and WiMAX transceivers operating in close proximity. In particular, embodiments provide filtering techniques to reject emissions from WiMAX into WiFi, and vice versa. The filtering techniques eliminate the need for additional isolation between WiMAX and WiFi antennas (approximately 50 dB), which is beyond what is achievable in practice. Embodiments can be tailored according to different use cases of the WiFi and WiMAX transceivers (e.g., fixed CPE, portable router, smart phone with tethering).

Wireless transceivers with filter arrangement for WiFi and WiMAX coexsistence

A phased array system having antennas, non-variable phase shifters, and switches. The non-variable phase shifters are configured to be coupled selectively to a transmitter or a receiver. A non-variable phase shifter is configured to shift a phase of an electromagnetic energy wave that traverses the non-variable phase shifter by a fraction of a period of the electromagnetic energy wave for a range of frequencies of the electromagnetic energy wave. At least one of the fraction and the range associated with the non-variable phase shifter is different from at least one of the fraction and the range associated with other non-variable phase shifters. The switches are configured to couple selectively the antennas to the non-variable phase shifters, the transmitter, or the receiver.

Phased array systems

An exercising device for gymnasium or playground structurally designed to support an occupant in a partially reclining position. The structure is basically conical and includes a personal support area surrounded by a structure support area that is designed for contact with the ground or floor surface. Suitable means are provided within the conical structure for the occupant to position his hands and feet so that the unit may be thereafter moved in a rotational fashion by shifting the center of gravity of the unit-occupant combination.

Space tumbler

A collapsible fish house that includes a base having a floor, interior walls inclined upwardly and outwardly of the floor, a perimetric top flange joined to the interior walls, exterior walls extending downwardly and outwardly of the top flange, and a horizontal perimetric flange joined to the lower edges of the exterior walls; a roof having a top wall provided with longitudinal ribs, and of a size and shape to overlay the top flange, roof walls sloped downwardly and outwardly of the roof top wall, and a perimetric portion joined to the lower edges of the last mentioned roof walls that in a fish house collapsed condition seats on the horizontal flange; collapsible walls made of, for example, canvas, having upper edges joined to the roof, lower edges joined to the top flange, and a closable entry; and telescopic poles having lower ends removably mounted by the base exterior of the canvas and upper ends removably mounted in holes in the roof to support the roof in an elevated condition relative the base. The floor is provided with depressed corner portions for having fish holes cut therethrough, and ridges that in conjunction with one of the interior walls surrounds the floor portion on which the stove is to be located.
