Abstract:
A method and system of adaptation of a linear equalizer using a virtual decision feedback equalizer (VDFE) are disclosed. In one embodiment, a method of adjusting a setting of a linear equalizer includes determining a change to a decision feedback equalizer (DFE) tap weight value of a predefined metric according to a data signal and an error signal (e.g., the change may be generated according to an average of a specified plurality of data signals and the error signal); using the change in the DFE tap weight value to algorithmically generate a modification in a linear equalizer setting; and adjusting the linear equalizer setting. The linear equalizer is located in a feed-forward path and/or a feedback path of data transmission. The linear equalizer may be located in a transmitter and/or a receiver. The linear equalizer may be a continuous time linear equalizer and/or a Finite Impulse Response (FIR) linear equalizer.

Abstract:
An electronic device (100) includes a housing (11) defining a mounting hole (1111), a key mechanism (10) mounted to the housing and partially exposed by the mounting hole, and a printed circuit board (20) received in the housing and corresponding to the key mechanism. The key mechanism includes a key body (13). The key body has a band (133) surrounding an edge thereof and is sealingly connected to the housing.
Abstract:
There is presently provided a stimulus-responsive polymer comprising a biodegradable polymer backbone and a stimulus-responsive pendant group attached to the biodegradable polymer backbone, wherein the biodegradable polymer backbone comprises a poly(amino ester) or a poly(amido amine), the poly(amido amine) optionally comprising a disulfide linkage in the backbone.
Abstract:
A fastener (35) includes a base (33), an orientation block (36), a located block (37) and two magnets (38, 39). The base includes a mounting portion (40) and a securing portion (50). The orientation block is slidably and rotatably connected to the securing portion. The located block is rotatably engaged in the mounting portion. One of the two magnets is disposed adjacent to the securing portion, the other magnet is disposed in the located block. The two magnets are attracted to each other configured for adjusting a distance between the orientation block and the located block.
Abstract:
A battery cover assembly (100) includes a housing (30), fixing assembly (40), cover (10) and button (20). The housing includes a receptacle (33) in a middle portion thereof; and two latch slots (37) defined in a bottom portion thereof The base board (50) is fixed to the housing, and with the housing defines a receiving cavity. The fixing assembly includes a sliding frame (41), slidably attached on the base board, and an elastic member (44). The sliding frame has a multiple clasps (423, 432). The cover is configured to be removable attached to the housing and defines a button slot (11) therein. The cover has a multiple claws (12, 13) and two latches (14). The button is mounted to the housing and cooperates with the sliding frame, the button extending through the button slot so as to be exposed to a user.
Abstract:
A hinge assembly (200) includes a housing (12), a shaft (11), a fixing pin (14), a transposition mechanism (13) and a first spring (16). The housing has a circumferential wall defining a manual slot (121) and an automatic slot (123). Each of the manual slot and the automatic slot runs through a circumferential wall thereof. The shaft defines a pin hole (1141), and the shaft is engaged in the housing. The fixing pin passes through the pin hole of the shaft. One end of the fixing pin is alternatively received in the manual slot or the automatic slot. The transposition mechanism is configured for switching the pin from the manual slot to the automatic slot. The first spring provides an elastic force causing the housing to move relative to the shaft when the pin breaks away from the manual slot.
