The cradle assembly includes a cradle base and a cradle rotatably attached to the cradle base. The cradle rotates such that the cell phone is located in either a portrait configuration or a landscape configuration. The cradle includes a pair of cradle arms and a pair of grips to hold the cell phone. The speaker assembly includes a speaker housing and one or more speakers located within the speaker housing. The cradle base includes a cradle release button that when pressed, releases the cradle assembly from the speaker assembly. The cradle arms and the grips creates a twist-to-release securement system such that when a user twists the cell phone in the cradle, the cell phone is released from the phone holder.

Abstract: The invention relates to magnetic field sensors in which magnetoresistance is used as the physical phenomenon for detecting and measuring the magnetic field. It consists in producing a stack comprising a first ferromagnetic layer (101), an insulating layer (103), a second ferromagnetic layer (102) and an antiferromagnetic layer (104). The two ferromagnetic layers exhibit crossed magnetic anisotropies and form with the insulating layer a tunnel junction. The anisotropy of the first layer is obtained from the shape energy of the substrate on which this first layer rests and which is slightly misoriented with respect thereto. The anisotropy of the second layer is obtained by the action of the antiferromagnetic layer.
